+## Ejemplo
+
+```typescript
+cn("px-4 py-2", "px-6")              // "px-6 py-2" (tailwind-merge resuelve conflicto)
+cn("text-red-500", false && "hidden") // "text-red-500" (clsx filtra falsy)
+cn("rounded-lg", className)           // composición con className externo
+```
+
+## Notas
+
+Base de todo el sistema de estilos. Todos los componentes la usan para componer className.
