### Overlay Lifecycle
Overlay components are disposed when closed. Don't reuse references - create fresh instances:
```typescript
// Wrong - stale reference
let menu: MenuComponent;
await ctx.ui.custom((_, __, ___, done) => {
menu = new MenuComponent(done);
return menu;
}, { overlay: true });
setActiveComponent(menu); // Disposed
// Correct - re-call to re-show
const showMenu = () => ctx.ui.custom((_, __, ___, done) =>
new MenuComponent(done), { overlay: true });
await showMenu(); // First show
await showMenu(); // "Back" = just call again
```
See [overlay-qa-tests.ts](../examples/extensions/overlay-qa-tests.ts) for comprehensive examples covering anchors, margins, stacking, responsive visibility, and animation.
