UI Feature Implementation

Single entry point for sidecar UI work. All new modals must use internal/modal. For complete keyboard shortcut listings, see references/keyboard-shortcuts-reference.md.

Quick Checklist

• Modals: use internal/modal, render with ui.OverlayModal, avoid manual hit region math
• Pills/chips/tabs: use styles.RenderPillWithStyle; auto-fallback when nerdFontsEnabled is false
• Keyboard: Commands + FocusContext + bindings must match; names short; priorities set
• Mouse: rebuild hit regions on each render; add general regions first, specific last
• Rendering: keep output within View width/height to avoid header/footer overlap. Use contentHeight := height - headerLines - footerLines
• Testing: verify keyboard, mouse, hover, scrolling, and footer hints
• Plugins must NOT render their own footer -- the app renders a unified footer from Commands()

Modals (internal/modal)

All new modals must use internal/modal. See docs/guides/deprecated/declarative-modal-guide.md for the full API.
