- Center ThothII logo + tagline; break "Human In The Loop" onto a second line
- Rename "New question" → "New session"; the button now clears the screen and
focuses the sticky bottom composer instead of opening a dialog
- Composer is always rendered and pinned at the bottom; typing the first
message there creates the session (no modal)
- Add inline stop control (square + inner circle) that interrupts and saves
the session via /close
- Always-present send affordance (CornerDownLeft ↵) on the right of the box
- Status footer under the box: mic (inert), model name, thinking level, and a
context-usage gauge (placeholder)
- Brand-tinted spinner beside the logo while the harness/backend holds the
ball; hidden once a widget needs human input
