14 * Run children in the terminal's alternate screen buffer, constrained to
15 * the viewport height. While mounted:
16 *
17 * - Enters the alt screen (DEC 1049), clears it, homes the cursor
18 * - Constrains its own height to the terminal row count, so overflow must
19 * be handled via `overflow: scroll` / flexbox (no native scrollback)
20 * - Optionally enables SGR mouse tracking (wheel + click/drag) — events
21 * surface as `ParsedKey` (wheel) and update the Ink instance's
22 * selection state (click/drag)
23 *
24 * On unmount, disables mouse tracking and exits the alt screen, restoring
25 * the main screen's content. Safe for use in ctrl-o transcript overlays
26 * and similar temporary fullscreen views — the main screen is preserved.
27 *
28 * Notifies the Ink instance via `setAltScreenActive()` so the renderer
29 * keeps the cursor inside the viewport (preventing the cursor-restore LF
30 * from scrolling content) and so signal-exit cleanup can exit the alt
31 * screen if the component's own unmount doesn't run.
