## How it operates [#how-it-operates]

Renderer contracts separate application behavior from backend mount, frame, layout projection, hit testing, terminal session, scheduling, and static-output concerns.

## API [#api]

No public declarations were discovered.

## Events and lifecycle [#events-and-lifecycle]

Backends consume normalized input and expose deterministic frame and lifecycle results.

All subscriptions and registrations return a disposer or belong to an owning
runtime that disposes them in reverse order.

## Example [#example]

```tsx
const registry = new RendererRegistry();
registry.register("cell", backend);
```
