+
+#### Key Points About `$component`:
+
+1. **Light DOM only** - No Shadow DOM, children are accessible and styleable from outside
+2. **Slot system** - `slot()` function filters child nodes by `slot` attribute
+3. **Reactive props** - Each observed attribute becomes a signal in the `props` object
+4. **Event emission** - `emit()` dispatches custom events with `detail` payload
+5. **Cleanup** - `onUnmount()` registers functions called when component is removed
+6. **Host access** - `host` gives direct access to the custom element instance
+
