+- **Prettier** – Automatically formats your template literals for better readability
+- **lit-html** – Adds syntax highlighting, autocompletion, and inline HTML color previews inside `html` tagged templates
+
+This combination gives you framework-level developer experience without the framework complexity—syntax highlighting, color previews, and automatic formatting for your reactive templates, all while writing pure JavaScript.
+
+```javascript
+// With lit-html extension, this gets full syntax highlighting and color previews!

+  <div style="color: #ff4444; background: linear-gradient(45deg, blue, green)">
+    <h1>Beautiful highlighted template</h1>
+  </div>
+`
+```
