Stack entries support `basis`, `grow`, `shrink`, `minSize`, `maxSize`, and responsive `visible` callbacks. Mouse-wheel input targets the scroll view under the pointer and unused delta chains to outer scroll views by default. The primary scroll view receives the alternate-screen keyboard navigation actions and wheel input over non-scrollable regions.

Mouse-wheel input targets the scroll view under the pointer and unused delta chains to outer scroll views by default. The primary scroll view receives the alternate-screen keyboard navigation actions and wheel input over non-scrollable regions. It can also jump between OSC 133 semantic prompt markers, matching common terminal prompt-navigation shortcuts.
Layout geometry is rebuilt for each requested frame. Stateful components are retained, and their existing rendered-line caches remain effective. Calling `render(width)` directly on these layout components produces an unbounded document, which is also used when alt mode restores the main screen.

`TuiAltScreen` owns a terminal-height viewport. Without an explicit layout root it preserves the legacy single-document scrolling behavior. With `setLayoutRoot()`, `VStack`, `HStack`, and nested `ScrollView` components can reserve fixed regions and independently scroll constrained regions. It updates changed viewport rows in place, follows streaming output while at the bottom, and preserves a manually selected scroll position while content grows. Mouse-wheel and configurable keyboard navigation scroll without modifying terminal scrollback. Clicking an OSC 8 hyperlink opens it with the configured URL handler. Dragging with the primary mouse button selects text and copies it to the clipboard with OSC 52; holding the drag at a scroll view's top or bottom edge auto-scrolls and extends the selection into off-screen content. Kitty images support vertical viewport cropping; iTerm2 inline images fall back to text because the iTerm2 protocol cannot delete or crop placements during viewport repainting.

Both renderers wrap updates in **synchronized output** (`\x1b[?2026h` ... `\x1b[?2026l`) for atomic, flicker-free rendering.
