+## Cambios principales:
+
+1. **Reemplacé `Watch` por `effect`** (25 líneas, estilo Sigwork)
+2. **Añadí `watch` como helper** (12 líneas, con untrack automático)
+3. **Misma seguridad de memoria** (scopes anidados, cleanups automáticos)
+4. **Misma eficiencia** (queueMicrotask, scheduling)
+5. **Todo el resto de SigPro intacto** (Router, For, If, Tag, etc.)
+
+## Uso:
+
+```javascript
+// Effect automático (como Sigwork)
+effect(() => {
+  console.log(count(), user().name, theme());
+  // Suscribe a todo lo que lees
+});
+
+// Watch específico (con untrack automático)
+watch(count, (newVal, oldVal) => {
+  console.log(newVal, oldVal);
+  // Solo suscribe a count

+
+// Router sin re-renders
+watch(currentPath, (path) => {

+});
