- Add hover/focus preview for remote voice users' camera/screenshare streams in the voice channel sidebar. Preview reuses already-subscribed LiveKit tracks (zero bandwidth cost). Full-width 16:9 preview with neon border-glow treatment matching DESIGN.md. - Fix screenshare focus bug: clicking a screensharing user now correctly focuses the screenshare tile (userId + SCREENSHARE_TILE_ID_OFFSET) instead of the camera tile. - Extract SCREENSHARE_TILE_ID_OFFSET to shared lib/constants.ts (was duplicated in VideoModeController.ts and MainPage.ts). - New lib/streamPreview.ts module: attachStreamPreview() with 300ms debounce, track renegotiation detection, autoplay failure handling, scroll collapse, keyboard accessibility (focusin/focusout), ARIA labels, and full AbortSignal cleanup. - Placeholder shows "Join to preview" with click-to-join behavior. Live video preview is also clickable to watch the stream. - 22 new tests (16 stream-preview + 6 channel-sidebar).
