- `TuiMainScreen` renders into the main terminal buffer and preserves terminal scrollback.
- `TuiAltScreen` renders a fixed-height viewport in the alternate terminal buffer with application-owned scrolling. When stopped, it restores the main buffer and prints the complete final document.
- `SwitchableTui` keeps one stable TUI while switching between main-screen and alternate-screen rendering. `ProcessTerminal` preserves its terminal lifecycle across switches.

```
Use `SwitchableTui` when the renderer must change without replacing references retained by components. `setMode()` returns `false` while an overlay is mounted. Custom terminals can implement the optional `suspendRenderer()` and `resumeRenderer()` hooks to preserve their lifecycle while moving screen-local modes; otherwise `SwitchableTui` stops and restarts them during a switch.
```typescript
import { SwitchableTui } from "@earendil-works/pi-tui";
const tui = new SwitchableTui(terminal, { mode: "main" });
tui.setLayoutRoot(fullscreenLayout);
tui.start();
tui.setMode("alternate");
tui.setMode("main");
```
### Alternate-screen viewport layouts
`TuiAltScreen` can render an explicit terminal-height layout. `VStack` and `HStack` allocate constrained regions, while `ScrollView` owns scrolling for one region. These semantics are intentionally unavailable on `TuiMainScreen`, where the terminal owns scrollback.
