- Stack textarea above button row on mobile (flex-direction: column)
- font-size: 16px on textarea prevents iOS Safari auto-zoom on focus
- body height: 100dvh adjusts dynamically as soft keyboard opens/closes
- Right col goes horizontal (row) with full width on mobile
- Hide height-row and enter-toggle (desktop-only concepts)
- Larger touch targets for Send/Stop/Note
- Hide session-id to reclaim vertical space
Desktop layout unchanged.
