3. **Normal Update**: Move the cursor to the first changed line, clear to the end, and render changed lines
`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, including jumps between OSC 133 semantic prompt markers. 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.
