+# Components API 🧩
+
+Components in SigPro are native Web Components built on the Custom Elements standard. They provide a way to create reusable, encapsulated pieces of UI with reactive properties and automatic cleanup.
+
+## `$.component(tagName, setupFunction, observedAttributes, useShadowDOM)`
+
+Creates a custom element with reactive properties and automatic dependency tracking.
+
+```javascript
+import { $, html } from 'sigpro';
+
+$.component('my-button', (props, { slot, emit }) => {
+  return html`
+    <button 
+      class="btn"
+      @click=${() => emit('click')}
+    >
+      ${slot()}
+    </button>
+  `;
+}, ['variant']); // Observe the 'variant' attribute
+```
+
+## 📋 API Reference
+
+### Parameters
+
+| Parameter | Type | Default | Description |
+|-----------|------|---------|-------------|
+| `tagName` | `string` | required | Custom element tag name (must include a hyphen, e.g., `my-button`) |
+| `setupFunction` | `Function` | required | Function that returns the component's template |
+| `observedAttributes` | `string[]` | `[]` | Attributes to observe for changes (become reactive props) |
+| `useShadowDOM` | `boolean` | `false` | `true` = Shadow DOM (encapsulated), `false` = Light DOM (inherits styles) |
+
+### Setup Function Parameters
+
+The setup function receives two arguments:
+
+1. **`props`** - Object containing reactive signals for each observed attribute
+2. **`context`** - Object with helper methods and properties
+
+#### Context Object Properties
+
+| Property | Type | Description |
+|----------|------|-------------|
+| `slot(name)` | `Function` | Returns array of child nodes for the specified slot |
+| `emit(name, detail)` | `Function` | Dispatches a custom event |
+| `select(selector)` | `Function` | Query selector within component's root |
+| `selectAll(selector)` | `Function` | Query selector all within component's root |
+| `host` | `HTMLElement` | Reference to the custom element instance |
+| `root` | `Node` | Component's root (shadow root or element itself) |
+| `onUnmount(callback)` | `Function` | Register cleanup function |
+
+## 🏠 Light DOM vs Shadow DOM
+
+### Light DOM (`useShadowDOM = false`) - Default
+
+The component **inherits global styles** from the application. Perfect for components that should integrate with your site's design system.
+
+```javascript
+// Button that uses global Tailwind CSS
+$.component('tw-button', (props, { slot, emit }) => {
+  const variant = props.variant() || 'primary';
+  
+  const variants = {
+    primary: 'bg-blue-500 hover:bg-blue-600 text-white',
+    secondary: 'bg-gray-500 hover:bg-gray-600 text-white',
+    outline: 'border border-blue-500 text-blue-500 hover:bg-blue-50'
+  };
+  
+  return html`
+    <button 
+      class="px-4 py-2 rounded font-semibold transition-colors ${variants[variant]}"
+      @click=${() => emit('click')}
+    >
+      ${slot()}
+    </button>
+  `;
+}, ['variant']);
+```
+
+### Shadow DOM (`useShadowDOM = true`) - Encapsulated
+
+The component **encapsulates its styles** completely. External styles don't affect it, and its styles don't leak out.
+
+```javascript
+// Calendar with encapsulated styles
+$.component('ui-calendar', (props) => {
+  return html`
+    <style>
+      /* These styles won't affect the rest of the page */
+      .calendar {
+        font-family: system-ui, sans-serif;
+        background: white;
+        border-radius: 12px;
+        padding: 20px;
+        box-shadow: 0 4px 12px rgba(0,0,0,0.1);
+      }
+      .day {
+        aspect-ratio: 1;
+        display: flex;
+        align-items: center;
+        justify-content: center;
+        cursor: pointer;
+        border-radius: 50%;
+      }
+      .day.selected {
+        background: #2196f3;
+        color: white;
+      }
+    </style>
+    
+    <div class="calendar">
+      ${renderCalendar(props.date())}
+    </div>
+  `;
+}, ['date'], true); // true = use Shadow DOM
+```
+
+## 🎯 Basic Examples
+
+### Simple Counter Component
+
+```javascript
+// counter.js
+$.component('my-counter', (props) => {
+  const count = $(0);
+  
+  return html`
+    <div class="counter">
+      <p>Count: ${count}</p>
+      <button @click=${() => count(c => c + 1)}>+</button>
+      <button @click=${() => count(c => c - 1)}>-</button>
+      <button @click=${() => count(0)}>Reset</button>
+    </div>
+  `;
+});
+```
+
+**Usage:**
+```html
+<my-counter></my-counter>
+```
+
+### Component with Props
+
+```javascript
+// greeting.js
+$.component('my-greeting', (props) => {
+  const name = props.name() || 'World';
+  const greeting = $(() => `Hello, ${name}!`);
+  
+  return html`
+    <div class="greeting">
+      <h1>${greeting}</h1>
+      <p>This is a greeting component.</p>
+    </div>
+  `;
+}, ['name']); // Observe the 'name' attribute
+```
+
+**Usage:**
+```html
+<my-greeting name="John"></my-greeting>
+<my-greeting name="Jane"></my-greeting>
+```
+
+### Component with Events
+
+```javascript
+// toggle.js
+$.component('my-toggle', (props, { emit }) => {
+  const isOn = $(props.initial() === 'on');
+  
+  const toggle = () => {
+    isOn(!isOn());
+    emit('toggle', { isOn: isOn() });
+    emit(isOn() ? 'on' : 'off');
+  };
+  
+  return html`
+    <button 
+      class="toggle ${() => isOn() ? 'active' : ''}"
+      @click=${toggle}
+    >
+      ${() => isOn() ? 'ON' : 'OFF'}
+    </button>
+  `;
+}, ['initial']);
+```
+
+**Usage:**
+```html
+<my-toggle 
+  initial="off"
+  @toggle=${(e) => console.log('Toggled:', e.detail)}
+  @on=${() => console.log('Turned on')}
+  @off=${() => console.log('Turned off')}
+></my-toggle>
+```
+
+## 🎨 Advanced Examples
+
+### Form Input Component
+
+```javascript
+// form-input.js
+$.component('form-input', (props, { emit }) => {
+  const value = $(props.value() || '');
+  const error = $(null);
+  const touched = $(false);
+  
+  // Validation effect
+  $.effect(() => {
+    if (props.pattern() && touched()) {
+      const regex = new RegExp(props.pattern());
+      const isValid = regex.test(value());
+      error(isValid ? null : props.errorMessage() || 'Invalid input');
+      emit('validate', { isValid, value: value() });
+    }
+  });
+  
+  const handleInput = (e) => {
+    value(e.target.value);
+    emit('update', e.target.value);
+  };
+  
+  const handleBlur = () => {
+    touched(true);
+  };
+  
+  return html`
+    <div class="form-group">

+      />
+      
+      ${() => error() ? html`

+## 🎯 Decision Guide: Light DOM vs Shadow DOM
+
+| Use Light DOM (`false`) when... | Use Shadow DOM (`true`) when... |
+|--------------------------------|-------------------------------|
+| Component is part of your main app | Building a UI library for others |
+| Using global CSS (Tailwind, Bootstrap) | Creating embeddable widgets |
+| Need to inherit theme variables | Styles must be pixel-perfect everywhere |
+| Working with existing design system | Component has complex, specific styles |
+| Quick prototyping | Distributing to different projects |
+| Form elements that should match site | Need style isolation/encapsulation |
+
+## 📊 Summary
+
+| Feature | Description |
+|---------|-------------|
+| **Native Web Components** | Built on Custom Elements standard |
+| **Reactive Props** | Observed attributes become signals |
+| **Two Rendering Modes** | Light DOM (default) or Shadow DOM |
+| **Automatic Cleanup** | Effects and listeners cleaned up on disconnect |
+| **Event System** | Custom events with `emit()` |
+| **Slot Support** | Full slot API for content projection |
+| **Zero Dependencies** | Pure vanilla JavaScript |
+
+---
+
+> **Pro Tip:** Start with Light DOM components for app-specific UI, and use Shadow DOM when building components that need to work identically across different projects or websites.

+# Fetch API 🌐
+
+SigPro provides a simple, lightweight wrapper around the native Fetch API that integrates seamlessly with signals for loading state management. It's designed for common use cases with sensible defaults.
+
+## Core Concepts
+
+### What is `$.fetch`?
+
+A ultra-simple fetch wrapper that:
+- **Automatically handles JSON** serialization and parsing
+- **Integrates with signals** for loading state
+- **Returns `null` on error** (no try/catch needed for basic usage)
+- **Works great with effects** for reactive data fetching
+
+## `$.fetch(url, data, [loading])`
+
+Makes a POST request with JSON data and optional loading signal.
+
+```javascript
+import { $ } from 'sigpro';
+
+const loading = $(false);
+
+async function loadUser() {
+  const user = await $.fetch('/api/user', { id: 123 }, loading);
+  if (user) {
+    console.log('User loaded:', user);
+  }
+}
+```
+
+## 📋 API Reference
+
+### Parameters
+
+| Parameter | Type | Description |
+|-----------|------|-------------|
+| `url` | `string` | Endpoint URL |
+| `data` | `Object` | Data to send (automatically JSON.stringify'd) |
+| `loading` | `Function` (optional) | Signal function to track loading state |
+
+### Returns
+
+| Return | Description |
+|--------|-------------|
+| `Promise<Object\|null>` | Parsed JSON response or `null` on error |
+
+## 🎯 Basic Examples
+
+### Simple Data Fetching
+
+```javascript
+import { $ } from 'sigpro';
+
+const userData = $(null);
+
+async function fetchUser(id) {
+  const data = await $.fetch('/api/user', { id });
+  if (data) {
+    userData(data);
+  }
+}
+
+fetchUser(123);
+```
+
+### With Loading State
+
+```javascript
+import { $, html } from 'sigpro';
+
+const user = $(null);
+const loading = $(false);
+
+async function loadUser(id) {
+  const data = await $.fetch('/api/user', { id }, loading);
+  if (data) user(data);
+}
+
+// In your template
+html`
+  <div>
+    ${() => loading() ? html`
+      <div class="spinner">Loading...</div>
+    ` : user() ? html`
+      <div>
+        <h2>${user().name}</h2>
+        <p>Email: ${user().email}</p>
+      </div>
+    ` : html`
+      <p>No user found</p>
+    `}
+  </div>
+`;
+```
+
+### In an Effect
+
+```javascript
+import { $ } from 'sigpro';
+
+const userId = $(1);
+const user = $(null);
+const loading = $(false);
+
+$.effect(() => {
+  const id = userId();
+  if (id) {
+    $.fetch(`/api/users/${id}`, null, loading).then(data => {
+      if (data) user(data);
+    });
+  }
+});
+
+userId(2); // Automatically fetches new user
+```
+
+## 🚀 Advanced Examples
+
+### User Profile with Loading States
+
+```javascript
+import { $, html } from 'sigpro';
+
+const Profile = () => {
+  const userId = $(1);
+  const user = $(null);
+  const loading = $(false);
+  const error = $(null);
+
+  const fetchUser = async (id) => {
+    error(null);
+    const data = await $.fetch('/api/user', { id }, loading);
+    if (data) {
+      user(data);
+    } else {
+      error('Failed to load user');
+    }
+  };
+
+  // Fetch when userId changes
+  $.effect(() => {
+    fetchUser(userId());
+  });
+
+  return html`
+    <div class="profile">
+      <div class="user-selector">
+        <button @click=${() => userId(1)}>User 1</button>
+        <button @click=${() => userId(2)}>User 2</button>
+        <button @click=${() => userId(3)}>User 3</button>
+      </div>
+
+      ${() => {
+        if (loading()) {
+          return html`<div class="spinner">Loading profile...</div>`;
+        }
+        
+        if (error()) {
+          return html`<div class="error">${error()}</div>`;
+        }
+        
+        if (user()) {
+          return html`
+            <div class="user-info">
+              <h2>${user().name}</h2>
+              <p>Email: ${user().email}</p>
+              <p>Role: ${user().role}</p>
+              <p>Joined: ${new Date(user().joined).toLocaleDateString()}</p>
+            </div>
+          `;
+        }
+        
+        return html`<p>Select a user</p>`;
+      }}
+    </div>
+  `;
+};

+          <button 
+            @click=${uploadFiles}
+            ?disabled=${uploading}
+          >
+            ${() => uploading() ? 'Uploading...' : 'Upload Files'}
+          </button>
+        </div>
+      ` : ''}
+      
+      ${() => uploadResults().length > 0 ? html`
+        <div class="upload-results">
+          <h3>Upload Results:</h3>
+          <ul>
+            ${uploadResults().map(result => html`
+              <li class="${result.success ? 'success' : 'error'}">
+                ${result.file}: 
+                ${result.success ? 'Uploaded successfully' : `Failed: ${result.error}`}
+              </li>
+            `)}
+          </ul>
+        </div>
+      ` : ''}
+    </div>
+  `;
+};
+```
+
+### Retry Logic
+
+```javascript
+import { $ } from 'sigpro';
+
+// Enhanced fetch with retry
+const fetchWithRetry = async (url, data, loading, maxRetries = 3) => {
+  let lastError;
+  
+  for (let attempt = 1; attempt <= maxRetries; attempt++) {
+    try {
+      if (loading) loading(true);
+      
+      const result = await $.fetch(url, data);
+      if (result !== null) {
+        return result;
+      }
+      
+      // If we get null but no error, wait and retry
+      if (attempt < maxRetries) {
+        await new Promise(resolve => 
+          setTimeout(resolve, Math.pow(2, attempt) * 1000) // Exponential backoff
+        );
+      }
+    } catch (error) {
+      lastError = error;
+      console.warn(`Attempt ${attempt} failed:`, error);
+      
+      if (attempt < maxRetries) {
+        await new Promise(resolve => 
+          setTimeout(resolve, Math.pow(2, attempt) * 1000)
+        );
+      }
+    } finally {
+      if (attempt === maxRetries && loading) {
+        loading(false);
+      }
+    }
+  }
+  
+  console.error('All retry attempts failed:', lastError);
+  return null;
+};
+
+// Usage
+const loading = $(false);
+const data = await fetchWithRetry('/api/unreliable-endpoint', {}, loading, 5);
+```
+
+## 🎯 Best Practices
+
+### 1. Always Handle Null Responses
+
+```javascript
+// ❌ Don't assume success
+const data = await $.fetch('/api/data');
+console.log(data.property); // Might throw if data is null
+
+// ✅ Check for null
+const data = await $.fetch('/api/data');
+if (data) {
+  console.log(data.property);
+} else {
+  showError('Failed to load data');
+}
+```
+
+### 2. Use with Effects for Reactivity
+
+```javascript
+// ❌ Manual fetching
+button.addEventListener('click', async () => {
+  const data = await $.fetch('/api/data');
+  updateUI(data);
+});
+
+// ✅ Reactive fetching
+const trigger = $(false);
+
+$.effect(() => {
+  if (trigger()) {
+    $.fetch('/api/data').then(data => {
+      if (data) updateUI(data);
+    });
+  }
+});
+
+trigger(true); // Triggers fetch
+```
+
+### 3. Combine with Loading Signals
+
+```javascript
+// ✅ Always show loading state
+const loading = $(false);
+const data = $(null);
+
+async function load() {
+  const result = await $.fetch('/api/data', {}, loading);
+  if (result) data(result);
+}
+
+// In template
+html`
+  <div>
+    ${() => loading() ? '<Spinner />' : 
+      data() ? '<Data />' : 
+      '<Empty />'}
+  </div>
+`;
+```
+
+### 4. Cancel In-flight Requests
+
+```javascript
+// ✅ Use AbortController with effects
+let controller;
+
+$.effect(() => {
+  if (controller) {
+    controller.abort();
+  }
+  
+  controller = new AbortController();
+  
+  fetch(url, { signal: controller.signal })
+    .then(res => res.json())
+    .then(data => {
+      if (!controller.signal.aborted) {
+        updateData(data);
+      }
+    });
+  
+  return () => controller.abort();
+});
+```
+
+## 📊 Error Handling
+
+### Basic Error Handling
+
+```javascript
+const data = await $.fetch('/api/data');
+if (!data) {
+  // Handle error (show message, retry, etc.)
+}
+```
+
+### With Error Signal
+
+```javascript
+const data = $(null);
+const error = $(null);
+const loading = $(false);
+
+async function loadData() {
+  error(null);
+  const result = await $.fetch('/api/data', {}, loading);
+  
+  if (result) {
+    data(result);
+  } else {
+    error('Failed to load data');
+  }
+}
+```
+---
+
+> **Pro Tip:** Combine `$.fetch` with `$.effect` and loading signals for a complete reactive data fetching solution. The loading signal integration makes it trivial to show loading states in your UI.

+# Pages API 📄
+
+Pages in SigPro are special components designed for route-based navigation with **automatic cleanup**. When you navigate away from a page, all signals, effects, and event listeners created within that page are automatically cleaned up - no memory leaks, no manual cleanup needed.
+
+## `$.page(setupFunction)`
+
+Creates a page with automatic cleanup of all signals and effects when navigated away.
+
+```javascript
+import { $, html } from 'sigpro';
+
+export default $.page(() => {
+  // All signals and effects created here
+  // will be automatically cleaned up on navigation
+  const count = $(0);
+  
+  $.effect(() => {
+    console.log(`Count: ${count()}`);
+  });
+  
+  return html`
+    <div>
+      <h1>My Page</h1>
+      <p>Count: ${count}</p>
+      <button @click=${() => count(c => c + 1)}>+</button>
+    </div>
+  `;
+});
+```
+
+## 📋 API Reference
+
+| Parameter | Type | Description |
+|-----------|------|-------------|
+| `setupFunction` | `Function` | Function that returns the page content. Receives context object with `params` and `onUnmount` |
+
+### Context Object Properties
+
+| Property | Type | Description |
+|----------|------|-------------|
+| `params` | `Object` | Route parameters passed to the page |
+| `onUnmount` | `Function` | Register cleanup callbacks (alternative to automatic cleanup) |
+
+## 🎯 Basic Usage
+
+### Simple Page
+
+```javascript
+// pages/home.js
+import { $, html } from 'sigpro';
+
+export default $.page(() => {
+  const title = $('Welcome to SigPro');
+  
+  return html`
+    <div class="home-page">
+      <h1>${title}</h1>
+      <p>This page will clean itself up when you navigate away.</p>
+    </div>
+  `;
+});
+```
+
+### Page with Route Parameters
+
+```javascript
+// pages/user.js
+import { $, html } from 'sigpro';
+
+export default $.page(({ params }) => {
+  // Access route parameters
+  const userId = params.id;
+  const userData = $(null);
+  const loading = $(false);
+  
+  // Auto-cleaned effect
+  $.effect(() => {
+    loading(true);
+    $.fetch(`/api/users/${userId}`, null, loading)
+      .then(data => userData(data));
+  });
+  
+  return html`
+    <div>
+      ${() => loading() ? html`
+        <div class="spinner">Loading...</div>
+      ` : html`
+        <h1>User Profile: ${userData()?.name}</h1>
+        <p>Email: ${userData()?.email}</p>
+      `}
+    </div>
+  `;
+});
+```
+
+## 🧹 Automatic Cleanup
+
+The magic of `$.page` is automatic cleanup. Everything created inside the page is tracked and cleaned up:
+
+```javascript
+export default $.page(() => {
+  // ✅ Signals are auto-cleaned
+  const count = $(0);
+  const user = $(null);
+  
+  // ✅ Effects are auto-cleaned
+  $.effect(() => {
+    document.title = `Count: ${count()}`;
+  });
+  
+  // ✅ Event listeners are auto-cleaned
+  window.addEventListener('resize', handleResize);
+  
+  // ✅ Intervals and timeouts are auto-cleaned
+  const interval = setInterval(() => {
+    refreshData();
+  }, 5000);
+  
+  return html`<div>Page content</div>`;
+});
+// When navigating away: all signals, effects, listeners, intervals STOP
+```
+
+## 📝 Manual Cleanup with `onUnmount`
+
+Sometimes you need custom cleanup logic. Use `onUnmount` for that:
+
+```javascript
+export default $.page(({ onUnmount }) => {
+  // WebSocket connection
+  const socket = new WebSocket('wss://api.example.com');
+  
+  socket.onmessage = (event) => {
+    updateData(JSON.parse(event.data));
+  };
+  
+  // Manual cleanup
+  onUnmount(() => {
+    socket.close();
+    console.log('WebSocket closed');
+  });
+  
+  return html`<div>Real-time updates</div>`;
+});
+```
+
+## 🔄 Integration with Router
+
+Pages are designed to work seamlessly with `$.router`:
+
+```javascript
+import { $, html } from 'sigpro';
+import HomePage from './pages/Home.js';
+import UserPage from './pages/User.js';
+import SettingsPage from './pages/Settings.js';
+
+const routes = [
+  { path: '/', component: HomePage },
+  { path: '/user/:id', component: UserPage },
+  { path: '/settings', component: SettingsPage },
+];
+
+// Mount router
+document.body.appendChild($.router(routes));
+```
+
+## 💡 Practical Examples
+
+### Example 1: Data Fetching Page
+
+```javascript
+// pages/posts.js
+export default $.page(({ params }) => {
+  const posts = $([]);
+  const loading = $(true);
+  const error = $(null);
+  
+  $.effect(() => {
+    fetch('/api/posts')
+      .then(res => res.json())
+      .then(data => {
+        posts(data);
+        loading(false);
+      })
+      .catch(err => {
+        error(err.message);
+        loading(false);
+      });
+  });
+  
+  return html`
+    <div class="posts-page">
+      <h1>Blog Posts</h1>
+      
+      ${() => loading() ? html`
+        <div class="loading">Loading posts...</div>
+      ` : error() ? html`
+        <div class="error">Error: ${error()}</div>
+      ` : html`
+        <div class="posts-grid">
+          ${posts().map(post => html`
+            <article class="post-card">
+              <h2>${post.title}</h2>
+              <p>${post.excerpt}</p>
+              <a href="#/post/${post.id}">Read more</a>
+            </article>
+          `)}
+        </div>
+      `}
+    </div>
+  `;
+});
+```
+
+### Example 2: Real-time Dashboard
+
+```javascript
+// pages/dashboard.js
+export default $.page(({ onUnmount }) => {
+  const metrics = $({
+    cpu: 0,
+    memory: 0,
+    requests: 0
+  });
+  
+  // Auto-refresh data
+  const refreshInterval = setInterval(async () => {
+    const data = await $.fetch('/api/metrics');
+    if (data) metrics(data);
+  }, 5000);
+  
+  // Manual cleanup for interval
+  onUnmount(() => clearInterval(refreshInterval));
+  
+  // Live clock
+  const currentTime = $(new Date());
+  const clockInterval = setInterval(() => {
+    currentTime(new Date());
+  }, 1000);
+  
+  onUnmount(() => clearInterval(clockInterval));
+  
+  return html`
+    <div class="dashboard">
+      <h1>System Dashboard</h1>
+      
+      <div class="time">
+        Last updated: ${() => currentTime().toLocaleTimeString()}
+      </div>
+      
+      <div class="metrics-grid">
+        <div class="metric-card">
+          <h3>CPU Usage</h3>
+          <p class="metric-value">${() => metrics().cpu}%</p>
+        </div>
+        <div class="metric-card">
+          <h3>Memory Usage</h3>
+          <p class="metric-value">${() => metrics().memory}%</p>
+        </div>
+        <div class="metric-card">
+          <h3>Requests/min</h3>
+          <p class="metric-value">${() => metrics().requests}</p>
+        </div>
+      </div>
+    </div>
+  `;
+});
+```
+
+### Example 3: Multi-step Form
+
+```javascript
+// pages/checkout.js
+export default $.page(({ onUnmount }) => {
+  const step = $(1);
+  const formData = $({
+    email: '',

+  });
+  
+  // Warn user before leaving
+  const handleBeforeUnload = (e) => {

+  };
+  
+  window.addEventListener('beforeunload', handleBeforeUnload);
+  onUnmount(() => {
+    window.removeEventListener('beforeunload', handleBeforeUnload);
+  });
+  
+  const nextStep = () => step(s => Math.min(s + 1, 3));
+  const prevStep = () => step(s => Math.max(s - 1, 1));
+  
+  return html`
+    <div class="checkout">
+      <h1>Checkout - Step ${step} of 3</h1>
+      
+      ${() => {

+        `}
+      </div>
+    </div>
+  `;
+});
+```
+
+### Example 4: Page with Tabs
+
+```javascript
+// pages/profile.js
+export default $.page(({ params }) => {
+  const activeTab = $('overview');
+  const userData = $(null);
+  
+  // Load user data
+  $.effect(() => {
+    $.fetch(`/api/users/${params.id}`)
+      .then(data => userData(data));
+  });
+  
+  const tabs = {
+    overview: () => html`
+      <div>
+        <h3>Overview</h3>
+        <p>Username: ${userData()?.username}</p>
+        <p>Member since: ${userData()?.joined}</p>
+      </div>
+    `,
+    posts: () => html`
+      <div>
+        <h3>Posts</h3>
+        ${userData()?.posts.map(post => html`
+          <div class="post">${post.title}</div>
+        `)}
+      </div>
+    `,
+    settings: () => html`
+      <div>
+        <h3>Settings</h3>
+        <label>
+          <input type="checkbox" :checked=${userData()?.emailNotifications} />
+          Email notifications
+        </label>
+      </div>
+    `
+  };
+  
+  return html`
+    <div class="profile-page">
+      <h1>${() => userData()?.name}</h1>
+      
+      <div class="tabs">
+        ${Object.keys(tabs).map(tab => html`
+          <button 
+            class:active=${() => activeTab() === tab}

+        ${() => tabs[activeTab()]()}
+      </div>
+    </div>
+  `;
+});
+```
+
+## 🎯 Advanced Patterns
+
+### Page with Nested Routes
+
+```javascript
+// pages/settings/index.js
+export default $.page(({ params }) => {
+  const section = params.section || 'general';
+  
+  const sections = {
+    general: () => import('./general.js').then(m => m.default),
+    security: () => import('./security.js').then(m => m.default),
+    notifications: () => import('./notifications.js').then(m => m.default)
+  };
+  
+  const currentSection = $(null);
+  
+  $.effect(() => {
+    sections[section]().then(comp => currentSection(comp));
+  });
+  
+  return html`
+    <div class="settings">
+      <nav>
+        <a href="#/settings/general">General</a>
+        <a href="#/settings/security">Security</a>
+        <a href="#/settings/notifications">Notifications</a>
+      </nav>
+      
+      <div class="content">
+        ${currentSection}
+      </div>
+    </div>
+  `;
+});
+```
+
+### Page with Authentication
+
+```javascript
+// pages/dashboard.js
+export default $.page(({ onUnmount }) => {
+  const isAuthenticated = $(false);
+  const authCheck = $.effect(() => {
+    const token = localStorage.getItem('token');
+    isAuthenticated(!!token);
+  });
+  
+  // Redirect if not authenticated
+  $.effect(() => {
+    if (!isAuthenticated()) {
+      $.router.go('/login');
+    }
+  });
+  
+  return html`
+    <div class="dashboard">
+      <h1>Protected Dashboard</h1>
+      <!-- Protected content -->
+    </div>
+  `;
+});
+```
+

+
+## 📡 Signals - `$(initialValue)`
+
+Creates a reactive value that notifies dependents when changed.
+
+| Pattern | Example | Description |
+|---------|---------|-------------|
+| **Basic Signal** | `const count = $(0)` | Create signal with initial value |
+| **Getter** | `count()` | Read current value |
+| **Setter** | `count(5)` | Set new value directly |
+| **Updater** | `count(prev => prev + 1)` | Update based on previous value |
+| **Computed** | `const full = $(() => first() + last())` | Auto-updating derived signal |
+
+### Examples
+
+```javascript
+// Basic signal
+const count = $(0);
+console.log(count()); // 0
+count(5);
+count(c => c + 1); // 6
+
+// Computed signal
+const firstName = $('John');
+const lastName = $('Doe');
+const fullName = $(() => `${firstName()} ${lastName()}`);
+console.log(fullName()); // "John Doe"
+firstName('Jane'); // fullName auto-updates to "Jane Doe"
+```
+
+## 🔄 Effects - `$.effect(fn)`
+
+Executes a function and automatically re-runs when its dependencies change.
+
+| Pattern | Example | Description |
+|---------|---------|-------------|
+| **Basic Effect** | `$.effect(() => console.log(count()))` | Run effect on dependency changes |
+| **Cleanup** | `$.effect(() => { timer = setInterval(...); return () => clearInterval(timer) })` | Return cleanup function |
+| **Stop Effect** | `const stop = $.effect(...); stop()` | Manually stop an effect |
+
+### Examples
+
+```javascript
+// Auto-running effect
+const count = $(0);
+$.effect(() => {
+  console.log(`Count is: ${count()}`);
+}); // Logs immediately and whenever count changes
+
+// Effect with cleanup
+const userId = $(1);
+$.effect(() => {
+  const id = userId();
+  const timer = setInterval(() => fetchUser(id), 5000);
+  return () => clearInterval(timer); // Cleanup before re-run
+});
+```
+
+## 📄 Pages - `$.page(setupFunction)`
+
+Creates a page with automatic cleanup of all signals and effects when navigated away.
+
+```javascript
+// pages/about.js
+import { $, html } from 'sigpro';
+
+export default $.page(() => {
+  const count = $(0);
+  
+  // Auto-cleaned on navigation
+  $.effect(() => {
+    document.title = `Count: ${count()}`;
+  });
+  
+  return html`
+    <div>
+      <h1>About Page</h1>
+      <p>Count: ${count}</p>
+      <button @click=${() => count(c => c + 1)}>+</button>
+    </div>
+  `;
+});
+```
+
+### With Parameters
+
+```javascript
+export default $.page(({ params, onUnmount }) => {
+  const userId = params.id;
+  
+  // Manual cleanup if needed
+  const interval = setInterval(() => refresh(), 10000);
+  onUnmount(() => clearInterval(interval));
+  
+  return html`<div>User: ${userId}</div>`;
+});
+```
+
+## 🧩 Components - `$.component(tagName, setup, observedAttributes, useShadowDOM)`
+
+Creates Custom Elements with reactive properties.
+
+### Parameters
+
+| Parameter | Type | Default | Description |
+|-----------|------|---------|-------------|
+| `tagName` | `string` | required | Custom element tag (must include hyphen) |
+| `setupFunction` | `Function` | required | Function that renders the component |
+| `observedAttributes` | `string[]` | `[]` | Attributes to observe for changes |
+| `useShadowDOM` | `boolean` | `false` | `true` = Shadow DOM (encapsulated), `false` = Light DOM |
+
+### Light DOM Example (Default)
+
+```javascript
+// button.js - inherits global styles
+$.component('my-button', (props, { slot, emit }) => {
+  return html`
+    <button 
+      class="px-4 py-2 bg-blue-500 text-white rounded"
+      @click=${() => emit('click')}
+    >
+      ${slot()}
+    </button>
+  `;
+}, ['variant']); // Observe 'variant' attribute
+```
+
+### Shadow DOM Example
+
+```javascript
+// calendar.js - encapsulated styles
+$.component('my-calendar', (props) => {
+  return html`
+    <style>
+      /* These styles are isolated */
+      .calendar {
+        background: white;
+        border-radius: 8px;
+        box-shadow: 0 2px 10px rgba(0,0,0,0.1);
+      }
+    </style>
+    <div class="calendar">
+      ${renderCalendar(props.date())}
+    </div>
+  `;
+}, ['date'], true); // true = use Shadow DOM
+```
+
+## 🌐 Router - `$.router(routes)`
+
+Creates a hash-based router with automatic page cleanup.
+
+### Route Definition
+
+```javascript
+const routes = [
+  // Simple routes
+  { path: '/', component: HomePage },
+  { path: '/about', component: AboutPage },
+  
+  // Routes with parameters
+  { path: '/user/:id', component: UserPage },
+  { path: '/user/:id/posts/:pid', component: PostPage },
+  
+  // RegExp routes for advanced matching
+  { path: /^\/posts\/(?<id>\d+)$/, component: PostPage },
+];
+```
+
+### Usage
+
+```javascript
+import { $, html } from 'sigpro';
+import Home from './pages/Home.js';
+import User from './pages/User.js';
+
+const router = $.router([
+  { path: '/', component: Home },
+  { path: '/user/:id', component: User },
+]);
+
+// Navigation
+$.router.go('/user/42');
+$.router.go('about'); // Same as '/about'
+
+// In templates
+html`
+  <nav>
+    <a href="#/">Home</a>
+    <a href="#/user/42">Profile</a>
+    <button @click=${() => $.router.go('/contact')}>
+      Contact
+    </button>
+  </nav>
+`;
+```
+
+## 📦 Storage - `$.storage(key, initialValue, [storage])`
+
+Persistent signal that syncs with localStorage or sessionStorage.
+
+```javascript
+// localStorage (default)
+const theme = $.storage('theme', 'light');
+const user = $.storage('user', null);
+const settings = $.storage('settings', { notifications: true });
+
+// sessionStorage
+const tempData = $.storage('temp', {}, sessionStorage);
+
+// Usage like a normal signal
+theme('dark'); // Auto-saves to localStorage
+console.log(theme()); // 'dark' (even after page refresh)
+```
+
+## 🌐 Fetch - `$.fetch(url, data, [loading])`
+
+Simple fetch wrapper with automatic JSON handling.
+
+```javascript
+const loading = $(false);
+
+async function loadUser(id) {
+  const user = await $.fetch(`/api/users/${id}`, null, loading);
+  if (user) userData(user);
+}
+
+// In template
+html`
+  <div>
+    ${() => loading() ? html`<spinner></spinner>` : html`
+      <p>${userData()?.name}</p>
+    `}
+  </div>
+`;
+```
+
+## 🎨 Template Literals - `` html`...` ``
+
+Creates reactive DOM fragments with directives.
+
+### Directives Reference
+
+| Directive | Example | Description |
+|-----------|---------|-------------|
+| **Event** | `@click=${handler}` | Add event listener |
+| **Two-way binding** | `:value=${signal}` | Bind signal to input value |
+| **Boolean attribute** | `?disabled=${signal}` | Toggle boolean attribute |
+| **Property** | `.scrollTop=${value}` | Set DOM property directly |
+| **Class toggle** | `class:active=${isActive}` | Toggle class conditionally |
+
+### Examples
+
+```javascript
+const text = $('');
+const isDisabled = $(false);
+const activeTab = $('home');
+
+html`
+  <!-- Event binding -->
+  <button @click=${() => count(c => c + 1)}>+</button>
+  
+  <!-- Two-way binding -->
+  <input :value=${text} />
+  <p>You typed: ${text}</p>
+  
+  <!-- Boolean attributes -->
+  <button ?disabled=${isDisabled}>Submit</button>
+  
+  <!-- Class toggles -->
+  <div class:active=${activeTab() === 'home'}>
+    Home content
+  </div>
+  
+  <!-- Property binding -->
+  <div .scrollTop=${scrollPosition}></div>
+`;
+```
+
+## 🎯 Complete Component Example
+
+```javascript
+import { $, html } from 'sigpro';
+
+// Create a component
+$.component('user-profile', (props, { slot, emit }) => {
+  // Reactive state

+# Routing API 🌐
+
+SigPro includes a simple yet powerful hash-based router designed for Single Page Applications (SPAs). It works everywhere with zero server configuration and integrates seamlessly with `$.page` for automatic cleanup.
+
+## Why Hash-Based Routing?
+
+Hash routing (`#/about`) works **everywhere** - no server configuration needed. Perfect for:
+- Static sites and SPAs
+- GitHub Pages, Netlify, any static hosting
+- Local development without a server
+- Projects that need to work immediately
+
+## `$.router(routes)`
+
+Creates a hash-based router that renders the matching component and handles navigation.
+
+```javascript
+import { $, html } from 'sigpro';
+import HomePage from './pages/Home.js';
+import AboutPage from './pages/About.js';
+import UserPage from './pages/User.js';
+
+const routes = [
+  { path: '/', component: HomePage },
+  { path: '/about', component: AboutPage },
+  { path: '/user/:id', component: UserPage },
+];
+
+// Mount the router
+document.body.appendChild($.router(routes));
+```
+
+## 📋 API Reference
+
+### `$.router(routes)`
+
+| Parameter | Type | Description |
+|-----------|------|-------------|
+| `routes` | `Array<Route>` | Array of route configurations |
+
+**Returns:** `HTMLDivElement` - Container that renders the current page
+
+### `$.router.go(path)`
+
+| Parameter | Type | Description |
+|-----------|------|-------------|
+| `path` | `string` | Route path to navigate to (automatically adds leading slash) |
+
+### Route Object
+
+| Property | Type | Description |
+|----------|------|-------------|
+| `path` | `string` or `RegExp` | Route pattern to match |
+| `component` | `Function` | Function that returns page content (receives `params`) |
+
+## 🎯 Route Patterns
+
+### String Paths (Simple Routes)
+
+```javascript
+const routes = [
+  // Static routes
+  { path: '/', component: HomePage },
+  { path: '/about', component: AboutPage },
+  { path: '/contact', component: ContactPage },
+  
+  // Routes with parameters
+  { path: '/user/:id', component: UserPage },
+  { path: '/user/:id/posts', component: UserPostsPage },
+  { path: '/user/:id/posts/:postId', component: PostPage },
+  { path: '/search/:query/page/:num', component: SearchPage },
+];
+```
+
+### RegExp Paths (Advanced Routing)
+
+```javascript
+const routes = [
+  // Match numeric IDs only
+  { path: /^\/users\/(?<id>\d+)$/, component: UserPage },
+  
+  // Match product slugs (letters, numbers, hyphens)
+  { path: /^\/products\/(?<slug>[a-z0-9-]+)$/, component: ProductPage },
+  
+  // Match blog posts by year/month
+  { path: /^\/blog\/(?<year>\d{4})\/(?<month>\d{2})$/, component: BlogArchive },
+  
+  // Match optional language prefix
+  { path: /^\/(?<lang>en|es|fr)?\/?about$/, component: AboutPage },
+  
+  // Match UUID format
+  { path: /^\/items\/(?<uuid>[0-9a-f]{8}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{12})$/, 
+    component: ItemPage },
+];
+```

+
+// Mount to DOM
+document.body.appendChild(router);
+```
+
+### Page Components with Parameters
+
+```javascript

+        <p>Email: ${userData().email}</p>
+      ` : html`<p>Loading...</p>`}
+    </div>
+  `;
+});
+```
+
+### Navigation
+
+```javascript
+import { $, html } from 'sigpro';
+

+      Go to About
+    </button>
+    
+    <button @click=${() => $.router.go('contact')}>
+      Go to Contact (auto-adds leading slash)
+    </button>
+  </nav>
+`;

+
+// Create and mount router
+const router = $.router(routes);
+document.body.appendChild(router);
+```
+
+### Nested Routes
+
+```javascript
+// pages/Settings.js (parent route)
+import { $, html } from 'sigpro';
+import SettingsGeneral from './settings/General.js';
+import SettingsSecurity from './settings/Security.js';

+
+### Protected Routes (Authentication)
+
+```javascript
+// auth.js
+import { $ } from 'sigpro';
+
+const isAuthenticated = $(false);
+const user = $(null);

+
+### Lazy Loading Routes
+
+```javascript
+// lazy.js
+export const lazy = (loader) => {
+  let component = null;
+  
+  return async (params) => {

+    }
+    return component(params);
+  };
+};
+```
+
+```javascript
+// main.js with lazy loading
+import { $, html } from 'sigpro';
+import { lazy } from './lazy.js';
+import Layout from './Layout.js';
+
+const routes = [
+  { path: '/', component: lazy(() => import('./pages/Home.js')) },
+  { path: '/about', component: lazy(() => import('./pages/About.js')) },
+  { path: '/dashboard', component: lazy(() => import('./pages/Dashboard.js')) },
+  { 
+    path: '/admin', 
+    component: lazy(() => import('./pages/Admin.js')),
+    // Show loading state
+    loading: () => html`<div class="loading">Loading admin panel...</div>`
+  },
+];
+
+// Wrap with layout
+const routesWithLayout = routes.map(route => ({
+  ...route,
+  component: (params) => Layout(route.component(params))
+}));
+
+document.body.appendChild($.router(routesWithLayout));
+```
+
+### Route Guards / Middleware
+
+```javascript
+// middleware.js
+export const withGuard = (component, guard) => (params) => {
+  const result = guard(params);
+  if (result === true) {
+    return component(params);
+  } else if (typeof result === 'string') {
+    $.router.go(result);
+    return null;
+  }
+  return result; // Custom component (e.g., AccessDenied)
+};
+
+// Guards
+export const roleGuard = (requiredRole) => (params) => {
+  const userRole = localStorage.getItem('userRole');
+  if (userRole === requiredRole) return true;
+  if (!userRole) return '/login';
+  return AccessDeniedPage(params);
+};
+
+export const authGuard = () => (params) => {
+  const token = localStorage.getItem('token');
+  return token ? true : '/login';
+};
+
+export const pendingChangesGuard = (hasPendingChanges) => (params) => {
+  if (hasPendingChanges()) {
+    return ConfirmLeavePage(params);
+  }
+  return true;
+};
+```
+
+```javascript
+// Usage
+import { withGuard, authGuard, roleGuard } from './middleware.js';
+
+const routes = [
+  { path: '/', component: HomePage },

+  { 
+    path: '/admin', 
+    component: withGuard(AdminPage, roleGuard('admin')) 
+  },
+];
+```
+
+## 📊 Route Matching Priority
+
+Routes are matched in the order they are defined. More specific routes should come first:
+
+```javascript
+const routes = [
+  // More specific first
+  { path: '/user/:id/edit', component: EditUserPage },
+  { path: '/user/:id/posts', component: UserPostsPage },
+  { path: '/user/:id', component: UserPage },
+  
+  // Static routes
+  { path: '/about', component: AboutPage },
+  { path: '/contact', component: ContactPage },
+  
+  // Catch-all last
+  { path: '/:path(.*)', component: NotFoundPage },
+];
+```
+
+## 🎯 Complete Example

+# Signals API 📡
+
+Signals are the heart of SigPro's reactivity system. They are reactive values that automatically track dependencies and notify subscribers when they change. This enables fine-grained updates without virtual DOM diffing.
+
+## Core Concepts
+
+### What is a Signal?
+
+A signal is a function that holds a value and notifies dependents when that value changes. Signals can be:
+
+- **Basic signals** - Hold simple values (numbers, strings, objects)
+- **Computed signals** - Derive values from other signals
+- **Persistent signals** - Automatically sync with localStorage/sessionStorage
+
+### How Reactivity Works
+
+SigPro uses automatic dependency tracking:
+
+1. When you read a signal inside an effect, the effect becomes a subscriber
+2. When the signal's value changes, all subscribers are notified
+3. Updates are batched using microtasks for optimal performance
+4. Only the exact nodes that depend on changed values are updated
+
+## `$(initialValue)`
+
+Creates a reactive signal. The behavior changes based on the type of `initialValue`:
+
+- If `initialValue` is a **function**, creates a computed signal
+- Otherwise, creates a basic signal
+
+```javascript
+import { $ } from 'sigpro';
+
+// Basic signal
+const count = $(0);
+
+// Computed signal
+const firstName = $('John');
+const lastName = $('Doe');
+const fullName = $(() => `${firstName()} ${lastName()}`);
+```
+
+## 📋 API Reference
+
+### Basic Signals
+
+| Pattern | Example | Description |
+|---------|---------|-------------|
+| Create | `const count = $(0)` | Create signal with initial value |
+| Get | `count()` | Read current value |
+| Set | `count(5)` | Set new value directly |
+| Update | `count(prev => prev + 1)` | Update based on previous value |
+
+### Computed Signals
+
+| Pattern | Example | Description |
+|---------|---------|-------------|
+| Create | `const total = $(() => price() * quantity())` | Derive value from other signals |
+| Get | `total()` | Read computed value (auto-updates) |
+
+### Signal Methods
+
+| Method | Description | Example |
+|--------|-------------|---------|
+| `signal()` | Gets current value | `count()` |
+| `signal(newValue)` | Sets new value | `count(5)` |
+| `signal(prev => new)` | Updates using previous value | `count(c => c + 1)` |
+
+## 🎯 Basic Examples
+
+### Counter Signal
+
+```javascript
+import { $ } from 'sigpro';
+
+const count = $(0);
+
+console.log(count()); // 0
+
+count(5);
+console.log(count()); // 5
+
+count(prev => prev + 1);
+console.log(count()); // 6
+```
+
+### Object Signal
+
+```javascript
+import { $ } from 'sigpro';
+
+const user = $({
+  name: 'John',
+  age: 30,
+  email: 'john@example.com'
+});
+
+// Read
+console.log(user().name); // 'John'
+
+// Update (immutable pattern)
+user({
+  ...user(),
+  age: 31
+});
+
+// Partial update with function
+user(prev => ({
+  ...prev,
+  email: 'john.doe@example.com'
+}));
+```
+
+### Array Signal
+
+```javascript
+import { $ } from 'sigpro';
+
+const todos = $(['Learn SigPro', 'Build an app']);
+
+// Add item
+todos([...todos(), 'Deploy to production']);
+
+// Remove item
+todos(todos().filter((_, i) => i !== 1));
+
+// Update item
+todos(todos().map((todo, i) => 
+  i === 0 ? 'Master SigPro' : todo
+));
+```
+
+## 🔄 Computed Signals
+
+Computed signals automatically update when their dependencies change:
+
+```javascript
+import { $ } from 'sigpro';
+
+const price = $(10);
+const quantity = $(2);
+const tax = $(0.21);
+
+// Computed signals
+const subtotal = $(() => price() * quantity());
+const taxAmount = $(() => subtotal() * tax());
+const total = $(() => subtotal() + taxAmount());
+
+console.log(total()); // 24.2
+
+price(15);
+console.log(total()); // 36.3 (automatically updated)
+
+quantity(3);
+console.log(total()); // 54.45 (automatically updated)
+```
+
+### Computed with Multiple Dependencies
+
+```javascript
+import { $ } from 'sigpro';
+
+const firstName = $('John');
+const lastName = $('Doe');
+const prefix = $('Mr.');
+
+const fullName = $(() => {
+  // Computed signals can contain logic
+  const name = `${firstName()} ${lastName()}`;
+  return prefix() ? `${prefix()} ${name}` : name;
+});
+
+console.log(fullName()); // 'Mr. John Doe'
+
+prefix('');
+console.log(fullName()); // 'John Doe'
+```
+
+### Computed with Conditional Logic
+
+```javascript
+import { $ } from 'sigpro';
+
+const user = $({ role: 'admin', permissions: [] });
+const isAdmin = $(() => user().role === 'admin');
+const hasPermission = $(() => 
+  isAdmin() || user().permissions.includes('edit')
+);
+
+console.log(hasPermission()); // true
+
+user({ role: 'user', permissions: ['view'] });
+console.log(hasPermission()); // false (can't edit)
+
+user({ role: 'user', permissions: ['view', 'edit'] });
+console.log(hasPermission()); // true (now has permission)
+```
+
+## 🧮 Advanced Signal Patterns
+
+### Derived State Pattern
+
+```javascript
+import { $ } from 'sigpro';
+
+// Shopping cart example
+const cart = $([
+  { id: 1, name: 'Product 1', price: 10, quantity: 2 },
+  { id: 2, name: 'Product 2', price: 15, quantity: 1 },
+]);
+
+// Derived values
+const itemCount = $(() => 
+  cart().reduce((sum, item) => sum + item.quantity, 0)
+);
+
+const subtotal = $(() => 
+  cart().reduce((sum, item) => sum + (item.price * item.quantity), 0)
+);
+
+const tax = $(() => subtotal() * 0.21);
+const total = $(() => subtotal() + tax());
+
+// Update cart
+cart([
+  ...cart(),
+  { id: 3, name: 'Product 3', price: 20, quantity: 1 }
+]);
+
+// All derived values auto-update
+console.log(itemCount()); // 4
+console.log(total()); // (10*2 + 15*1 + 20*1) * 1.21 = 78.65
+```
+
+### Validation Pattern
+
+```javascript
+import { $ } from 'sigpro';
+
+const email = $('');
+const password = $('');
+const confirmPassword = $('');
+
+// Validation signals
+const isEmailValid = $(() => {
+  const value = email();
+  return /^[^\s@]+@[^\s@]+\.[^\s@]+$/.test(value);
+});
+
+const isPasswordValid = $(() => {
+  const value = password();
+  return value.length >= 8;
+});
+
+const doPasswordsMatch = $(() => 
+  password() === confirmPassword()
+);
+
+const isFormValid = $(() => 
+  isEmailValid() && isPasswordValid() && doPasswordsMatch()
+);
+
+// Update form
+email('user@example.com');
+password('secure123');
+confirmPassword('secure123');
+
+console.log(isFormValid()); // true
+
+// Validation messages
+const emailError = $(() => 
+  email() && !isEmailValid() ? 'Invalid email format' : ''
+);
+```
+
+### Filtering and Search Pattern
+
+```javascript
+import { $ } from 'sigpro';
+
+const items = $([
+  { id: 1, name: 'Apple', category: 'fruit' },
+  { id: 2, name: 'Banana', category: 'fruit' },
+  { id: 3, name: 'Carrot', category: 'vegetable' },
+  { id: 4, name: 'Date', category: 'fruit' },
+]);
+
+const searchTerm = $('');
+const categoryFilter = $('all');
+
+// Filtered items (computed)
+const filteredItems = $(() => {
+  let result = items();
+  
+  // Apply search filter
+  if (searchTerm()) {
+    const term = searchTerm().toLowerCase();
+    result = result.filter(item => 
+      item.name.toLowerCase().includes(term)
+    );
+  }
+  
+  // Apply category filter
+  if (categoryFilter() !== 'all') {
+    result = result.filter(item => 
+      item.category === categoryFilter()
+    );
+  }
+  
+  return result;
+});
+
+// Stats
+const fruitCount = $(() => 
+  items().filter(item => item.category === 'fruit').length
+);
+
+const vegCount = $(() => 
+  items().filter(item => item.category === 'vegetable').length
+);
+
+// Update filters
+searchTerm('a');
+console.log(filteredItems().map(i => i.name)); // ['Apple', 'Banana', 'Carrot', 'Date']
+
+categoryFilter('fruit');
+console.log(filteredItems().map(i => i.name)); // ['Apple', 'Banana', 'Date']
+```
+
+### Pagination Pattern
+
+```javascript
+import { $ } from 'sigpro';
+
+const allItems = $([...Array(100).keys()].map(i => `Item ${i + 1}`));
+const currentPage = $(1);
+const itemsPerPage = $(10);
+
+// Paginated items (computed)
+const paginatedItems = $(() => {
+  const start = (currentPage() - 1) * itemsPerPage();
+  const end = start + itemsPerPage();
+  return allItems().slice(start, end);
+});
+
+// Pagination metadata
+const totalPages = $(() => 
+  Math.ceil(allItems().length / itemsPerPage())
+);
+
+const hasNextPage = $(() => 
+  currentPage() < totalPages()
+);
+
+const hasPrevPage = $(() => 
+  currentPage() > 1
+);
+
+const pageRange = $(() => {
+  const current = currentPage();
+  const total = totalPages();
+  const delta = 2;
+  
+  let range = [];
+  for (let i = Math.max(2, current - delta); 
+       i <= Math.min(total - 1, current + delta); 
+       i++) {
+    range.push(i);
+  }
+  
+  if (current - delta > 2) range = ['...', ...range];
+  if (current + delta < total - 1) range = [...range, '...'];
+  
+  return [1, ...range, total];
+});
+
+// Navigation
+const nextPage = () => {
+  if (hasNextPage()) currentPage(c => c + 1);
+};
+
+const prevPage = () => {
+  if (hasPrevPage()) currentPage(c => c - 1);
+};
+
+const goToPage = (page) => {
+  if (page >= 1 && page <= totalPages()) {
+    currentPage(page);
+  }
+};
+```

+Signals use `Object.is` for change detection. Only notify subscribers when values are actually different:
+
+```javascript
+import { $ } from 'sigpro';
+
+const count = $(0);
+
+// These won't trigger updates:
+count(0); // Same value
+count(prev => prev); // Returns same value
+
+// These will trigger updates:
+count(1); // Different value
+count(prev => prev + 0); // Still 0? Actually returns 0? Wait...
+// Be careful with functional updates!
+```
+
+### Batch Updates
+
+Multiple signal updates are batched into a single microtask:
+
+```javascript
+import { $ } from 'sigpro';
+
+const firstName = $('John');
+const lastName = $('Doe');
+const fullName = $(() => `${firstName()} ${lastName()}`);
+
+$.effect(() => {
+  console.log('Full name:', fullName());
+});
+// Logs: 'Full name: John Doe'
+
+// Multiple updates in same tick - only one effect run!
+firstName('Jane');
+lastName('Smith');
+// Only logs once: 'Full name: Jane Smith'
+```
+
+### Infinite Loop Protection
+
+SigPro includes protection against infinite reactive loops:
+
+```javascript
+import { $ } from 'sigpro';
+
+const a = $(1);
+const b = $(2);
+
+// This would create a loop, but SigPro prevents it
+$.effect(() => {
+  a(b()); // Reading b
+  b(a()); // Reading a - loop detected!
+});
+// Throws: "SigPro: Infinite reactive loop detected."
+```
+
+## 📊 Performance Characteristics
+
+| Operation | Complexity | Notes |
+|-----------|------------|-------|
+| Signal read | O(1) | Direct value access |
+| Signal write | O(n) | n = number of subscribers |
+| Computed read | O(1) or O(m) | m = computation complexity |
+| Effect run | O(s) | s = number of signal reads |
+
+## 🎯 Best Practices
+
+### 1. Keep Signals Focused
+
+```javascript
+// ❌ Avoid large monolithic signals
+const state = $({
+  user: null,
+  posts: [],
+  theme: 'light',
+  notifications: []
+});
+
+// ✅ Split into focused signals
+const user = $(null);
+const posts = $([]);
+const theme = $('light');
+const notifications = $([]);
+```
+
+### 2. Use Computed for Derived State
+
+```javascript
+// ❌ Don't compute in templates/effects
+$.effect(() => {
+  const total = items().reduce((sum, i) => sum + i.price, 0);
+  updateUI(total);
+});
+
+// ✅ Compute with signals
+const total = $(() => items().reduce((sum, i) => sum + i.price, 0));
+$.effect(() => updateUI(total()));
+```
+
+### 3. Immutable Updates
+
+```javascript
+// ❌ Don't mutate objects/arrays
+const user = $({ name: 'John' });
+user().name = 'Jane'; // Won't trigger updates!
+
+// ✅ Create new objects/arrays
+user({ ...user(), name: 'Jane' });
+
+// ❌ Don't mutate arrays
+const todos = $(['a', 'b']);
+todos().push('c'); // Won't trigger updates!
+
+// ✅ Create new arrays
+todos([...todos(), 'c']);
+```
+
+### 4. Functional Updates for Dependencies
+
+```javascript
+// ❌ Avoid if new value depends on current
+count(count() + 1);
+
+// ✅ Use functional update
+count(prev => prev + 1);
+```
+
+### 5. Clean Up Effects
+
+```javascript
+import { $ } from 'sigpro';
+
+const userId = $(1);
+
+// Effects auto-clean in pages, but you can stop manually
+const stop = $.effect(() => {
+  fetchUser(userId());
+});
+
+// Later, if needed
+stop();
+```
+
+## 🚀 Real-World Examples
+
+### Form State Management
+
+```javascript
+import { $ } from 'sigpro';
+
+// Form state
+const formData = $({
+  username: '',
+  email: '',

+
+// Validation rules
+const validations = {
+  username: (value) => 
+    value.length >= 3 ? null : 'Username must be at least 3 characters',

+};
+
+// Validation signals
+const errors = $(() => {

+  }
+});
+
+// Form submission
+const submitAttempts = $(0);
+const isSubmitting = $(false);
+
+const handleSubmit = async () => {

+    touched(Object.keys(formData()).reduce((acc, field) => ({
+      ...acc,
+      [field]: true
+    }), {}));
+    return;
+  }
+  
+  isSubmitting(true);
+  try {
+    await saveForm(formData());
+    // Reset form on success

+## 📈 Debugging Signals
+
+### Logging Signal Changes
+
+```javascript
+import { $ } from 'sigpro';
+
+// Wrap a signal to log changes
+const withLogging = (signal, name) => {
+  return (...args) => {
+    if (args.length) {
+      const oldValue = signal();
+      const result = signal(...args);
+      console.log(`${name}:`, oldValue, '->', signal());
+      return result;
+    }
+    return signal();
+  };
+};
+
+// Usage
+const count = withLogging($(0), 'count');
+count(5); // Logs: "count: 0 -> 5"
+```
+
+### Signal Inspector
+
+```javascript
+import { $ } from 'sigpro';
+
+// Create an inspectable signal
+const createInspector = () => {
+  const signals = new Map();
+  
+  const createSignal = (initialValue, name) => {
+    const signal = $(initialValue);
+    signals.set(signal, { name, subscribers: new Set() });
+    
+    // Wrap to track subscribers
+    const wrapped = (...args) => {
+      if (!args.length && activeEffect) {
+        const info = signals.get(wrapped);
+        info.subscribers.add(activeEffect);
+      }
+      return signal(...args);
+    };
+    
+    return wrapped;
+  };
+  
+  const getInfo = () => {
+    const info = {};
+    signals.forEach((data, signal) => {
+      info[data.name] = {
+        subscribers: data.subscribers.size,
+        value: signal()
+      };
+    });
+    return info;
+  };
+  
+  return { createSignal, getInfo };
+};
+
+// Usage
+const inspector = createInspector();
+const count = inspector.createSignal(0, 'count');
+const doubled = inspector.createSignal(() => count() * 2, 'doubled');
+
+console.log(inspector.getInfo());
+// { count: { subscribers: 0, value: 0 }, doubled: { subscribers: 0, value: 0 } }

+# Storage API 💾
+
+SigPro provides persistent signals that automatically synchronize with browser storage APIs. This allows you to create reactive state that survives page reloads and browser sessions with zero additional code.
+
+## Core Concepts
+
+### What is Persistent Storage?
+
+Persistent signals are special signals that:
+- **Initialize from storage** (localStorage/sessionStorage) if a saved value exists
+- **Auto-save** whenever the signal value changes
+- **Handle JSON serialization** automatically
+- **Clean up** when set to `null` or `undefined`
+
+### Storage Types
+
+| Storage | Persistence | Use Case |
+|---------|-------------|----------|
+| `localStorage` | Forever (until cleared) | User preferences, themes, saved data |
+| `sessionStorage` | Until tab/window closes | Form drafts, temporary state |
+
+## `$.storage(key, initialValue, [storage])`
+
+Creates a persistent signal that syncs with browser storage.
+
+```javascript
+import { $ } from 'sigpro';
+
+// localStorage (default)
+const theme = $.storage('theme', 'light');
+const user = $.storage('user', null);
+const settings = $.storage('settings', { notifications: true });
+
+// sessionStorage
+const draft = $.storage('draft', '', sessionStorage);
+const formData = $.storage('form', {}, sessionStorage);
+```
+
+## 📋 API Reference
+
+### Parameters
+
+| Parameter | Type | Default | Description |
+|-----------|------|---------|-------------|
+| `key` | `string` | required | Storage key name |
+| `initialValue` | `any` | required | Default value if none stored |
+| `storage` | `Storage` | `localStorage` | Storage type (`localStorage` or `sessionStorage`) |
+
+### Returns
+
+| Return | Description |
+|--------|-------------|
+| `Function` | Signal function (getter/setter) with persistence |
+
+## 🎯 Basic Examples
+
+### Theme Preference
+
+```javascript
+import { $, html } from 'sigpro';
+
+// Persistent theme signal
+const theme = $.storage('theme', 'light');
+
+// Apply theme to document
+$.effect(() => {
+  document.body.className = `theme-${theme()}`;
+});
+
+// Toggle theme
+const toggleTheme = () => {
+  theme(t => t === 'light' ? 'dark' : 'light');
+};
+
+// Template
+html`
+  <div>
+    <p>Current theme: ${theme}</p>
+    <button @click=${toggleTheme}>
+      Toggle Theme
+    </button>
+  </div>
+`;
+```
+
+### User Preferences
+
+```javascript
+import { $ } from 'sigpro';
+
+// Complex preferences object
+const preferences = $.storage('preferences', {
+  language: 'en',
+  fontSize: 'medium',
+  notifications: true,
+  compactView: false,
+  sidebarOpen: true
+});
+
+// Update single preference
+const setPreference = (key, value) => {
+  preferences({
+    ...preferences(),
+    [key]: value
+  });
+};
+
+// Usage
+setPreference('language', 'es');
+setPreference('fontSize', 'large');
+console.log(preferences().language); // 'es'
+```
+
+### Form Draft
+
+```javascript
+import { $, html } from 'sigpro';
+
+// Session-based draft (clears when tab closes)
+const draft = $.storage('contact-form', {
+  name: '',
+  email: '',
+  message: ''
+}, sessionStorage);
+
+// Auto-save on input
+const handleInput = (field, value) => {
+  draft({
+    ...draft(),
+    [field]: value
+  });
+};
+
+// Clear draft after submit
+const handleSubmit = async () => {
+  await submitForm(draft());
+  draft(null); // Clears from storage
+};
+
+// Template
+html`
+  <form @submit=${handleSubmit}>
+    <input
+      type="text"
+      :value=${() => draft().name}
+      @input=${(e) => handleInput('name', e.target.value)}
+      placeholder="Name"
+    />
+    <input
+      type="email"
+      :value=${() => draft().email}
+      @input=${(e) => handleInput('email', e.target.value)}
+      placeholder="Email"
+    />
+    <textarea
+      :value=${() => draft().message}
+      @input=${(e) => handleInput('message', e.target.value)}
+      placeholder="Message"
+    ></textarea>
+    <button type="submit">Send</button>
+  </form>
+`;
+```
+
+## 🚀 Advanced Examples
+
+### Authentication State
+
+```javascript
+import { $, html } from 'sigpro';
+
+// Persistent auth state
+const auth = $.storage('auth', {
+  token: null,
+  user: null,
+  expiresAt: null
+});
+
+// Computed helpers
+const isAuthenticated = $(() => {
+  const { token, expiresAt } = auth();
+  if (!token || !expiresAt) return false;
+  return new Date(expiresAt) > new Date();
+});
+
+const user = $(() => auth().user);
+
+// Login function
+const login = async (email, password) => {
+  const response = await fetch('/api/login', {
+    method: 'POST',
+    body: JSON.stringify({ email, password })
+  });
+  
+  if (response.ok) {
+    const { token, user, expiresIn } = await response.json();
+    auth({
+      token,
+      user,
+      expiresAt: new Date(Date.now() + expiresIn * 1000).toISOString()
+    });
+    return true;
+  }
+  return false;
+};
+
+// Logout
+const logout = () => {
+  auth(null); // Clear from storage
+};
+
+// Auto-refresh token
+$.effect(() => {
+  if (!isAuthenticated()) return;
+  
+  const { expiresAt } = auth();
+  const expiresIn = new Date(expiresAt) - new Date();
+  const refreshTime = expiresIn - 60000; // 1 minute before expiry
+  
+  if (refreshTime > 0) {
+    const timer = setTimeout(refreshToken, refreshTime);
+    return () => clearTimeout(timer);
+  }
+});
+
+// Navigation guard
+$.effect(() => {
+  if (!isAuthenticated() && window.location.pathname !== '/login') {
+    $.router.go('/login');
+  }
+});
+```
+
+### Multi-tab Synchronization
+
+```javascript
+import { $ } from 'sigpro';
+
+// Storage key for cross-tab communication
+const STORAGE_KEY = 'app-state';
+
+// Create persistent signal
+const appState = $.storage(STORAGE_KEY, {
+  count: 0,
+  lastUpdated: null
+});
+
+// Listen for storage events (changes from other tabs)
+window.addEventListener('storage', (event) => {
+  if (event.key === STORAGE_KEY && event.newValue) {
+    try {
+      // Update signal without triggering save loop
+      const newValue = JSON.parse(event.newValue);
+      appState(newValue);
+    } catch (e) {
+      console.error('Failed to parse storage event:', e);
+    }
+  }
+});
+
+// Update state (syncs across all tabs)
+const increment = () => {
+  appState({
+    count: appState().count + 1,
+    lastUpdated: new Date().toISOString()
+  });
+};
+
+// Tab counter
+const tabCount = $(1);
+
+// Track number of tabs open
+window.addEventListener('storage', (event) => {
+  if (event.key === 'tab-heartbeat') {
+    tabCount(parseInt(event.newValue) || 1);
+  }
+});
+
+// Send heartbeat
+setInterval(() => {
+  localStorage.setItem('tab-heartbeat', tabCount());
+}, 1000);
+```
+
+### Settings Manager
+
+```javascript
+import { $, html } from 'sigpro';
+
+// Settings schema
+const settingsSchema = {
+  theme: {
+    type: 'select',
+    options: ['light', 'dark', 'system'],
+    default: 'system'
+  },
+  fontSize: {
+    type: 'range',
+    min: 12,
+    max: 24,
+    default: 16
+  },
+  notifications: {
+    type: 'checkbox',
+    default: true
+  },
+  language: {
+    type: 'select',
+    options: ['en', 'es', 'fr', 'de'],
+    default: 'en'
+  }
+};
+
+// Persistent settings
+const settings = $.storage('app-settings', 
+  Object.entries(settingsSchema).reduce((acc, [key, config]) => ({
+    ...acc,
+    [key]: config.default
+  }), {})
+);
+
+// Settings component
+const SettingsPanel = () => {
+  return html`
+    <div class="settings-panel">
+      <h2>Settings</h2>
+      
+      ${Object.entries(settingsSchema).map(([key, config]) => {
+        switch(config.type) {
+          case 'select':
+            return html`
+              <div class="setting">
+                <label>${key}:</label>
+                <select 
+                  :value=${() => settings()[key]}
+                  @change=${(e) => updateSetting(key, e.target.value)}
+                >
+                  ${config.options.map(opt => html`
+                    <option value="${opt}" ?selected=${() => settings()[key] === opt}>
+                      ${opt}
+                    </option>
+                  `)}
+                </select>
+              </div>
+            `;
+            
+          case 'range':
+            return html`
+              <div class="setting">

+
+## 🛡️ Error Handling
+
+### Storage Errors
+
+```javascript
+import { $ } from 'sigpro';
+
+// Safe storage wrapper
+const safeStorage = (key, initialValue, storage = localStorage) => {
+  try {
+    return $.storage(key, initialValue, storage);
+  } catch (error) {
+    console.warn(`Storage failed for ${key}, using in-memory fallback:`, error);
+    return $(initialValue);
+  }
+};
+
+// Usage with fallback
+const theme = safeStorage('theme', 'light');
+const user = safeStorage('user', null);
+```
+
+### Quota Exceeded Handling
+
+```javascript
+import { $ } from 'sigpro';
+
+const createManagedStorage = (key, initialValue, maxSize = 1024 * 100) => { // 100KB limit
+  const signal = $.storage(key, initialValue);
+  
+  // Monitor size
+  const size = $(0);
+  
+  $.effect(() => {
+    try {
+      const value = signal();
+      const json = JSON.stringify(value);
+      const bytes = new Blob([json]).size;
+      
+      size(bytes);
+      
+      if (bytes > maxSize) {
+        console.warn(`Storage for ${key} exceeded ${maxSize} bytes`);
+        // Could implement cleanup strategy here
+      }
+    } catch (e) {
+      console.error('Size check failed:', e);
+    }
+  });
+  
+  return { signal, size };
+};
+
+// Usage
+const { signal: largeData, size } = createManagedStorage('app-data', {}, 50000);
+```
+
+## 📊 Storage Limits
+
+| Storage Type | Typical Limit | Notes |
+|--------------|---------------|-------|
+| `localStorage` | 5-10MB | Varies by browser |
+| `sessionStorage` | 5-10MB | Cleared when tab closes |
+| `cookies` | 4KB | Not recommended for SigPro |
+
+## 🎯 Best Practices
+
+### 1. Validate Stored Data
+
+```javascript
+import { $ } from 'sigpro';
+
+// Schema validation
+const createValidatedStorage = (key, schema, defaultValue, storage) => {
+  const signal = $.storage(key, defaultValue, storage);
+  
+  // Wrap to validate on read/write
+  const validated = (...args) => {
+    if (args.length) {
+      // Validate before writing
+      const value = args[0];
+      if (typeof value === 'function') {
+        // Handle functional updates
+        return validated(validated());
+      }
+      
+      // Basic validation
+      const isValid = Object.keys(schema).every(key => {
+        const validator = schema[key];
+        return !validator || validator(value[key]);
+      });
+      
+      if (!isValid) {
+        console.warn('Invalid data, skipping storage write');
+        return signal();
+      }
+    }
+    
+    return signal(...args);
+  };
+  
+  return validated;
+};
+
+// Usage
+const userSchema = {
+  name: v => v && v.length > 0,
+  age: v => v >= 18 && v <= 120,
+  email: v => /@/.test(v)
+};
+
+const user = createValidatedStorage('user', userSchema, {
+  name: '',
+  age: 25,
+  email: ''
+});
+```
+
+### 2. Handle Versioning
+
+```javascript
+import { $ } from 'sigpro';
+
+const VERSION = 2;
+
+const createVersionedStorage = (key, migrations, storage) => {
+  const raw = $.storage(key, { version: VERSION, data: {} }, storage);
+  
+  const migrate = (data) => {
+    let current = data;
+    const currentVersion = current.version || 1;
+    
+    for (let v = currentVersion; v < VERSION; v++) {
+      const migrator = migrations[v];
+      if (migrator) {
+        current = migrator(current);
+      }
+    }
+    
+    return current;
+  };
+  
+  // Migrate if needed
+  const stored = raw();
+  if (stored.version !== VERSION) {
+    const migrated = migrate(stored);
+    raw(migrated);
+  }
+  
+  return raw;
+};
+
+// Usage
+const migrations = {
+  1: (old) => ({
+    version: 2,
+    data: {
+      ...old.data,
+      preferences: old.preferences || {}
+    }
+  })
+};
+
+const settings = createVersionedStorage('app-settings', migrations);
+```
+
+### 3. Encrypt Sensitive Data
+
+```javascript
+import { $ } from 'sigpro';
+
+// Simple encryption (use proper crypto in production)
+const encrypt = (text) => {
+  return btoa(text); // Base64 - NOT secure, just example
+};
+
+const decrypt = (text) => {
+  try {
+    return atob(text);
+  } catch {
+    return null;
+  }
+};
+
+const createSecureStorage = (key, initialValue, storage) => {
+  const encryptedKey = `enc_${key}`;
+  const signal = $.storage(encryptedKey, null, storage);
+  
+  const secure = (...args) => {
+    if (args.length) {
+      // Encrypt before storing
+      const value = args[0];
+      const encrypted = encrypt(JSON.stringify(value));
+      return signal(encrypted);
+    }
+    
+    // Decrypt when reading
+    const encrypted = signal();
+    if (!encrypted) return initialValue;
+    
+    try {
+      const decrypted = decrypt(encrypted);
+      return decrypted ? JSON.parse(decrypted) : initialValue;
+    } catch {
+      return initialValue;
+    }
+  };
+  
+  return secure;
+};
+
+// Usage
+const secureToken = createSecureStorage('auth-token', null);
+secureToken('sensitive-data-123'); // Stored encrypted
+```
+
+## 📈 Performance Considerations
+
+| Operation | Cost | Notes |
+|-----------|------|-------|
+| Initial read | O(1) | Single storage read |
+| Write | O(1) + JSON.stringify | Auto-save on change |
+| Large objects | O(n) | Stringify/parse overhead |
+| Multiple keys | O(k) | k = number of keys |
+
+---
+
+> **Pro Tip:** Use `sessionStorage` for temporary data like form drafts, and `localStorage` for persistent user preferences. Always validate data when reading from storage to handle corrupted values gracefully.

+# Getting Started with SigPro 🚀
+
+Welcome to SigPro! This guide will help you get up and running with the library in minutes. SigPro is a minimalist reactive library that embraces the web platform - no compilation, no virtual DOM, just pure JavaScript and intelligent reactivity.
+
+## 📦 Installation
+
+Choose your preferred installation method:
+
+```bash
+# Using npm
+npm install sigpro
+
+# Using bun
+bun add sigpro
+
+# Or simply copy sigpro.js to your project
+# (yes, it's that simple!)
+```
+
+## 🎯 Core Imports
+
+```javascript
+import { $, html } from 'sigpro';
+```
+
+That's it! Just two imports to unlock the entire reactive system:
+- **`$`** - Creates reactive signals (the heart of reactivity)
+- **`html`** - Template literal tag for reactive DOM rendering
+
+## 🧠 Understanding the Basics
+
+### Signals - The Reactive Heart
+
+Signals are reactive values that automatically track dependencies and update when changed:
+
+```javascript
+// Create a signal with initial value
+const count = $(0);
+
+// Read value (with auto dependency tracking)
+console.log(count()); // 0
+
+// Set new value
+count(5);
+
+// Update using previous value
+count(prev => prev + 1); // 6
+
+// Create computed signals (auto-updating)
+const firstName = $('John');
+const lastName = $('Doe');
+const fullName = $(() => `${firstName()} ${lastName()}`);
+console.log(fullName()); // "John Doe"
+firstName('Jane'); // fullName() now returns "Jane Doe"
+```
+
+### Effects - Automatic Reactions
+
+Effects automatically run and re-run when their signal dependencies change:
+
+```javascript
+const count = $(0);
+
+$.effect(() => {
+  console.log(`Count is: ${count()}`);
+});
+// Logs: "Count is: 0"
+
+count(1);
+// Logs: "Count is: 1"
+
+// Effects can return cleanup functions
+$.effect(() => {
+  const id = count();
+  const timer = setInterval(() => {
+    console.log(`Polling with count: ${id}`);
+  }, 1000);
+  
+  // Cleanup runs before next effect execution
+  return () => clearInterval(timer);
+});
+```
+
+### Rendering with `html`
+
+The `html` tag creates reactive DOM fragments:
+
+```javascript
+const count = $(0);
+const isActive = $(true);
+
+const fragment = html`
+  <div class="counter">
+    <h2>Count: ${count}</h2>
+    
+    <!-- Event binding -->
+    <button @click=${() => count(c => c + 1)}>
+      Increment
+    </button>
+    
+    <!-- Boolean attributes -->
+    <button ?disabled=${() => !isActive()}>
+      Submit
+    </button>
+  </div>
+`;
+
+document.body.appendChild(fragment);
+```
+
+## 🎨 Your First Reactive App
+
+Let's build a simple todo app to see SigPro in action:
+
+```javascript
+import { $, html } from 'sigpro';
+
+// Create a simple todo app
+function TodoApp() {
+  // Reactive state
+  const todos = $(['Learn SigPro', 'Build something awesome']);
+  const newTodo = $('');
+  
+  // Computed value
+  const todoCount = $(() => todos().length);
+  
+  // Add todo function
+  const addTodo = () => {
+    if (newTodo().trim()) {
+      todos([...todos(), newTodo()]);
+      newTodo('');
+    }
+  };
+  
+  // Remove todo function
+  const removeTodo = (index) => {
+    todos(todos().filter((_, i) => i !== index));
+  };
+  
+  // Return reactive template
+  return html`
+    <div style="max-width: 400px; margin: 2rem auto; font-family: system-ui;">
+      <h1>📝 Todo App</h1>
+      
+      <!-- Input form -->
+      <div style="display: flex; gap: 8px; margin-bottom: 16px;">
+        <input 
+          type="text" 
+          :value=${newTodo}
+          placeholder="Add a new todo..."
+          style="flex: 1; padding: 8px; border: 1px solid #ddd; border-radius: 4px;"
+          @keydown.enter=${addTodo}
+        />
+        <button

+```
+
+## 🎯 Key Concepts
+
+### 1. **Signal Patterns**
+
+| Pattern | Example | Use Case |
+|---------|---------|----------|
+| Basic signal | `const count = $(0)` | Simple values |
+| Computed | `$( () => first() + last() )` | Derived values |
+| Signal update | `count(5)` | Direct set |
+| Functional update | `count(prev => prev + 1)` | Based on previous |
+
+### 2. **Effect Patterns**
+
+```javascript
+// Basic effect
+$.effect(() => console.log(count()));
+
+// Effect with cleanup
+$.effect(() => {
+  const timer = setInterval(() => {}, 1000);
+  return () => clearInterval(timer);
+});
+
+// Stopping an effect
+const stop = $.effect(() => {});
+stop(); // Effect won't run again
+```
+
+### 3. **HTML Directives**
+
+| Directive | Example | Description |
+|-----------|---------|-------------|
+| `@event` | `@click=${handler}` | Event listeners |
+| `:property` | `:value=${signal}` | Two-way binding |
+| `?attribute` | `?disabled=${signal}` | Boolean attributes |
+| `.property` | `.scrollTop=${value}` | DOM properties |
+
+## 💡 Pro Tips for Beginners
+
+### 1. **Start Simple**
+```javascript
+// Begin with basic signals
+const name = $('World');
+html`<h1>Hello, ${name}!</h1>`;
+```
+
+### 2. **Use Computed Signals for Derived State**
+```javascript
+// ❌ Don't compute in template
+html`<p>Total: ${items().length * price()}</p>`;
+
+// ✅ Compute with signals
+const total = $(() => items().length * price());
+html`<p>Total: ${total}</p>`;
+```
+
+### 3. **Leverage Effects for Side Effects**
+```javascript
+// Auto-save to localStorage
+$.effect(() => {
+  localStorage.setItem('draft', JSON.stringify(draft()));
+});
+```
+
+## 🔧 VS Code Setup
+
+For the best development experience, install these VS Code extensions:
+
+- **lit-html** - Adds syntax highlighting for `html` tagged templates
+- **Prettier** - Automatically formats your template literals
+
+```javascript
+// With lit-html extension, you get full syntax highlighting!
+html`
+  <div style="color: #ff4444; background: linear-gradient(45deg, blue, green)">
+    <h1>Beautiful highlighted template</h1>
+  </div>
+`
+```
+
+## 📁 Project Structure
+
+Here's a recommended structure for larger apps:
+
+```
+my-sigpro-app/
+├── index.html
+├── main.js
+├── components/
+│   ├── Button.js
+│   ├── TodoList.js
+│   └── TodoItem.js
+├── pages/
+│   ├── HomePage.js
+│   └── AboutPage.js
+└── utils/
+    └── helpers.js
+```

+# Why SigPro? ❓
+
+After years of building applications with React, Vue, and Svelte—investing countless hours mastering their unique mental models, build tools, and update cycles—I kept circling back to the same realization: no matter how sophisticated the framework, it all eventually compiles down to HTML, CSS, and vanilla JavaScript. The web platform has evolved tremendously, yet many libraries continue to reinvent the wheel, creating parallel universes with their own rules, their own syntaxes, and their own steep learning curves.
+
+**SigPro is my answer to a simple question:** Why fight the platform when we can embrace it?
+
+## 🌐 The Web Platform Is Finally Ready
+
+Modern browsers now offer powerful primitives that make true reactivity possible without virtual DOM diffing, without compilers, and without lock-in:
+
+| Browser Primitive | What It Enables |
+|-------------------|-----------------|
+| **Custom Elements** | Create reusable components with native browser APIs |
+| **Shadow DOM** | Encapsulate styles and markup without preprocessors |
+| **CSS Custom Properties** | Dynamic theming without CSS-in-JS |
+| **Microtask Queues** | Efficient update batching without complex scheduling |
+
+## 🎯 The SigPro Philosophy
+
+SigPro strips away the complexity, delivering a reactive programming model that feels familiar but stays remarkably close to vanilla JS:
+
+- **No JSX transformations** - Just template literals
+- **No template compilers** - The browser parses your HTML
+- **No proprietary syntax to learn** - Just functions and signals
+- **No build step required** - Works directly in the browser
+
+```javascript
+// Just vanilla JavaScript with signals
+import { $, html } from 'sigpro';
+
+const count = $(0);
+
+document.body.appendChild(html`
+  <div>
+    <p>Count: ${count}</p>
+    <button @click=${() => count(c => c + 1)}>
+      Increment
+    </button>
+  </div>
+`);
+```
+
+## 📊 Comparative

+| **Longevity** (standards-based) | 🥇 **10+ years** | 🥈 5 years | 🥉 3 years | 🥈 5 years | 🥈 5 years |
+
+## 🔑 Core Principles
+
+SigPro is built on four fundamental principles:
+
+### 📡 **True Reactivity**
+Automatic dependency tracking with no manual subscriptions. When a signal changes, only the exact DOM nodes that depend on it update—surgically, efficiently, instantly.
+
+### ⚡ **Surgical Updates**
+No virtual DOM diffing. No tree reconciliation. Just direct DOM updates where and when needed. The result is predictable performance that scales with your content, not your component count.
+
+### 🧩 **Web Standards**
+Built on Custom Elements, not a custom rendering engine. Your components are real web components that work in any framework—or none at all.
+
+### 🔬 **Predictable**
+No magic, just signals and effects. What you see is what you get. The debugging experience is straightforward because there's no framework layer between your code and the browser.
+
+## 🎨 The Development Experience
+
+```javascript
+// With VS Code + lit-html extension, you get:
+// ✅ Syntax highlighting
+// ✅ Color previews
+// ✅ Auto-formatting
+// ✅ IntelliSense
+
+html`
+  <div style="color: #ff4444; background: linear-gradient(45deg, blue, green)">
+    <h1>Beautiful highlighted template</h1>
+  </div>
+`
+```
+
+## ⏱️ Built for the Long Term
+
+What emerged is a library that proves we've reached a turning point: the web is finally mature enough that we don't need to abstract it anymore. We can build reactive, component-based applications using virtually pure JavaScript, leveraging the platform's latest advances instead of working against them.
+
+**The result isn't just smaller bundles or faster rendering—it's code that will still run 10 years from now, in any browser, without maintenance.**
+
+## 📈 The Verdict
+
+While other frameworks build parallel universes with proprietary syntax and compilation steps, SigPro embraces the web platform. SigPro isn't just another framework—it's a return to fundamentals, showing that the dream of simple, powerful reactivity is now achievable with the tools browsers give us out of the box.

+# Vite Plugin: Automatic File-based Routing 🚦
+
+SigPro provides an optional Vite plugin that automatically generates routes based on your file structure. No configuration needed - just create pages and they're instantly available with the correct paths.
+
+## Why Use This Plugin?
+
+While SigPro's router works perfectly with manually defined routes, this plugin:
+- **Eliminates boilerplate** - No need to write route configurations
+- **Enforces conventions** - Consistent URL structure across your app
+- **Supports dynamic routes** - Use `[param]` syntax for parameters
+- **Automatic code-splitting** - Each page becomes a separate chunk
+- **Type-safe** (with JSDoc) - Routes follow your file structure
+
+## Installation
+
+The plugin is included with SigPro, but you need to add it to your Vite config:
+
+```javascript
+// vite.config.js
+import { defineConfig } from 'vite';
+import { sigproRouter } from 'sigpro';
+
+export default defineConfig({
+  plugins: [sigproRouter()]
+});
+```
+
+## How It Works
+
+The plugin scans your `src/pages` directory and automatically generates routes based on the file structure:
+
+```
+src/pages/
+├── index.js              →  '/'
+├── about.js              →  '/about'
+├── blog/
+│   ├── index.js          →  '/blog'
+│   └── [slug].js         →  '/blog/:slug'
+└── users/
+    ├── [id].js           →  '/users/:id'
+    └── [id]/edit.js      →  '/users/:id/edit'
+```
+
+## Usage
+
+### 1. Enable the Plugin
+
+Add the plugin to your Vite config as shown above.
+
+### 2. Import the Generated Routes
+
+Once you have the generated routes, using them with the router is straightforward:
+
+```javascript
+// main.js
+import { $, html } from 'sigpro';
+import { routes } from 'virtual:sigpro-routes';
+
+// Simple usage
+const router = $.router(routes);
+document.body.appendChild(router);
+```
+
+Or directly in your template:
+
+```javascript
+// app.js
+import { $, html } from 'sigpro';
+import { routes } from 'virtual:sigpro-routes';
+
+const App = () => html`
+  <div class="app">
+    <header>
+      <h1>My Application</h1>
+    </header>
+    
+    <main class="p-4 flex flex-col gap-4 mx-auto w-full">
+      <div class="p-4 bg-base-100 rounded-box shadow-sm">
+        ${$.router(routes)}
+      </div>
+    </main>
+  </div>
+`;
+
+document.body.appendChild(App());
+```
+
+This approach keeps your template clean and lets the router handle all the page rendering automatically.
+
+### 3. Create Pages
+
+```javascript
+// src/pages/index.js
+import { $, html } from 'sigpro';
+
+export default () => {
+  return html`
+    <div>
+      <h1>Home Page</h1>
+      <a href="#/about">About</a>
+    </div>
+  `;
+};
+```
+
+```javascript
+// src/pages/users/[id].js
+import { $, html } from 'sigpro';
+
+export default (params) => {
+  const userId = params.id;
+  
+  return html`
+    <div>
+      <h1>User Profile: ${userId}</h1>
+      <a href="#/users/${userId}/edit">Edit</a>
+    </div>
+  `;
+};
+```
+
+## 📋 File-to-Route Mapping
+
+### Static Routes
+
+| File Path | Generated Route |
+|-----------|-----------------|
+| `src/pages/index.js` | `/` |
+| `src/pages/about.js` | `/about` |
+| `src/pages/contact/index.js` | `/contact` |
+| `src/pages/blog/post.js` | `/blog/post` |
+
+### Dynamic Routes
+
+| File Path | Generated Route | Example URL |
+|-----------|-----------------|-------------|
+| `src/pages/users/[id].js` | `/users/:id` | `/users/42` |
+| `src/pages/blog/[slug].js` | `/blog/:slug` | `/blog/hello-world` |
+| `src/pages/users/[id]/posts/[pid].js` | `/users/:id/posts/:pid` | `/users/42/posts/123` |
+
+### Nested Routes
+
+| File Path | Generated Route | Notes |
+|-----------|-----------------|-------|
+| `src/pages/settings/index.js` | `/settings` | Index page |
+| `src/pages/settings/profile.js` | `/settings/profile` | Sub-page |
+| `src/pages/settings/security.js` | `/settings/security` | Sub-page |
+| `src/pages/settings/[section].js` | `/settings/:section` | Dynamic section |
+
+## 🎯 Advanced Examples
+
+### Blog with Posts
+
+```javascript
+// src/pages/blog/index.js - Lists all posts
+export default () => {
+  const posts = $([]);
+  
+  $.effect(() => {
+    fetch('/api/posts')
+      .then(res => res.json())
+      .then(data => posts(data));
+  });
+  
+  return html`
+    <div>
+      <h1>Blog</h1>
+      ${posts().map(post => html`
+        <article>
+          <h2><a href="#/blog/${post.slug}">${post.title}</a></h2>
+          <p>${post.excerpt}</p>
+        </article>
+      `)}
+    </div>
+  `;
+};
+```
+
+```javascript
+// src/pages/blog/[slug].js - Single post
+export default (params) => {
+  const post = $(null);
+  const slug = params.slug;
+  
+  $.effect(() => {
+    fetch(`/api/posts/${slug}`)
+      .then(res => res.json())
+      .then(data => post(data));
+  });
+  
+  return html`
+    <div>
+      <a href="#/blog">← Back to blog</a>
+      ${() => post() ? html`
+        <article>
+          <h1>${post().title}</h1>
+          <div>${post().content}</div>
+        </article>
+      ` : html`<div>Loading...</div>`}
+    </div>
+  `;
+};
+```
+
+### Dashboard with Nested Sections
+
+```javascript
+// src/pages/dashboard/index.js
+export default () => {
+  return html`
+    <div class="dashboard">
+      <nav>
+        <a href="#/dashboard">Overview</a>
+        <a href="#/dashboard/analytics">Analytics</a>
+        <a href="#/dashboard/settings">Settings</a>
+      </nav>
+      <main>
+        <h1>Dashboard Overview</h1>
+        <!-- Overview content -->
+      </main>
+    </div>
+  `;
+};
+```
+
+```javascript
+// src/pages/dashboard/analytics.js
+export default () => {
+  return html`
+    <div class="dashboard">
+      <nav>
+        <a href="#/dashboard">Overview</a>
+        <a href="#/dashboard/analytics">Analytics</a>
+        <a href="#/dashboard/settings">Settings</a>
+      </nav>
+      <main>
+        <h1>Analytics</h1>
+        <!-- Analytics content -->
+      </main>
+    </div>
+  `;
+};
+```
+
+### E-commerce Product Routes
+
+```javascript
+// src/pages/products/[category]/[id].js
+export default (params) => {
+  const { category, id } = params;
+  const product = $(null);
+  
+  $.effect(() => {
+    fetch(`/api/products/${category}/${id}`)
+      .then(res => res.json())
+      .then(data => product(data));
+  });
+  
+  return html`
+    <div class="product-page">
+      <nav class="breadcrumbs">
+        <a href="#/products">Products</a> &gt;
+        <a href="#/products/${category}">${category}</a> &gt;
+        <span>${id}</span>
+      </nav>
+      
+      ${() => product() ? html`
+        <div class="product">
+          <h1>${product().name}</h1>
+          <p class="price">$${product().price}</p>
+          <p>${product().description}</p>
+          <button @click=${() => addToCart(product())}>
+            Add to Cart
+          </button>
+        </div>
+      ` : html`<div>Loading...</div>`}
+    </div>
+  `;
+};
+```
+
+## 🔧 Configuration Options
+
+The plugin accepts an optional configuration object:
+
+```javascript
+// vite.config.js
+import { defineConfig } from 'vite';
+import { sigproRouter } from 'sigpro/vite';
+
+export default defineConfig({
+  plugins: [
+    sigproRouter({
+      pagesDir: 'src/pages',      // Default: 'src/pages'
+      extensions: ['.js', '.jsx'], // Default: ['.js', '.jsx']
+      exclude: ['**/_*', '**/components/**'] // Glob patterns to exclude
+    })
+  ]
+});
+```
+
+### Options
+
+| Option | Type | Default | Description |
+|--------|------|---------|-------------|
+| `pagesDir` | `string` | `'src/pages'` | Directory containing your pages |
+| `extensions` | `string[]` | `['.js', '.jsx']` | File extensions to include |
+| `exclude` | `string[]` | `[]` | Glob patterns to exclude |
+
+## 🎯 Route Priority
+
+The plugin automatically sorts routes to ensure correct matching:
+
+1. **Static routes** take precedence over dynamic ones
+2. **More specific routes** (deeper paths) come first
+3. **Alphabetical order** for routes at the same level
+
+Example sorting:
+```
+/users/new           (static, specific)
+/users/[id]/edit     (dynamic, deeper)
+/users/[id]          (dynamic, shallower)
+/users/profile       (static, shallower)
+```
+
+## 📦 Output Example
+
+When you import `virtual:sigpro-routes`, you get:
+
+```javascript
+// Generated module
+import Page_0 from '/src/pages/index.js';
+import Page_1 from '/src/pages/about.js';
+import Page_2 from '/src/pages/blog/index.js';
+import Page_3 from '/src/pages/blog/[slug].js';
+import Page_4 from '/src/pages/users/[id].js';
+import Page_5 from '/src/pages/users/[id]/edit.js';
+
+export const routes = [
+  { path: '/', component: Page_0 },
+  { path: '/about', component: Page_1 },
+  { path: '/blog', component: Page_2 },
+  { path: '/blog/:slug', component: Page_3 },
+  { path: '/users/:id', component: Page_4 },
+  { path: '/users/:id/edit', component: Page_5 },
+];
+```
+
+## 🚀 Performance Benefits
+
+- **Automatic code splitting** - Each page becomes a separate chunk
+- **Lazy loading ready** - Import pages dynamically
+- **Tree shaking** - Only used routes are included
+
+```javascript
+// With dynamic imports (automatic with Vite)
+const routes = [
+  { path: '/', component: () => import('./pages/index.js') },
+  { path: '/about', component: () => import('./pages/about.js') },
+  // ...
+];
+```
+
+## 💡 Pro Tips
+
+### 1. Group Related Pages
+
+```
+src/pages/
+├── dashboard/
+│   ├── index.js
+│   ├── analytics.js
+│   └── settings.js
+└── dashboard.js   # ❌ Don't mix with folder
+```
+
+### 2. Use Index Files for Clean URLs
+
+```
+✅ Good:
+pages/blog/index.js      → /blog
+pages/blog/post.js       → /blog/post
+
+❌ Avoid:
+pages/blog.js            → /blog (conflicts with folder)
+```
+
+### 3. Private Components
+
+Prefix with underscore to exclude from routing:
+
+```
+src/pages/
+├── index.js
+├── about.js
+└── _components/         # ❌ Not scanned
+    └── Header.js
+```
+
+### 4. Layout Components
+
+Create a layout wrapper in your main entry:
+
+```javascript
+// main.js
+import { $, html } from 'sigpro';
+import { routes } from 'virtual:sigpro-routes';
+
+// Wrap all routes with layout
+const routesWithLayout = routes.map(route => ({
+  ...route,
+  component: (params) => Layout(route.component(params))
+}));
+
+const router = $.router(routesWithLayout);
+document.body.appendChild(router);
+```
+
+---
+
+> **Note:** This plugin is completely optional. You can always define routes manually if you prefer. The plugin just saves you from writing boilerplate route configurations.
+
+> **Pro Tip:** The plugin works great with hot module replacement (HMR) - add a new page and it's instantly available in your dev server without restarting!
