Header:
- Sessions, ⚙ context panel, ≡ settings dropdown (Files, Account,
Sign Out), and ❓ help — down from 6+ individual buttons
- Responsive: flex-row on desktop, wraps on mobile with labels hidden
Footer (input area):
- 4-way mode select replaces the button row — shows only the active
mode as [icon] [label] ▲; click opens an upward dropdown
- Options sorted by MRU: most recently used floats to the bottom
(closest to the trigger button) for quick re-selection
- Current mode marked with ✓
- Note mode shows a small prv/pub sub-toggle below the select button
- Mobile: textarea on top (full width), mode select + send on one row
Mode state consolidated from 3 booleans into a single current_mode
variable with localStorage persistence and MRU tracking.
