- Replace height <select> with S/M/L buttons (data-height); active class shows
current setting; clicking an empty textarea briefly expands it as a preview
so the effect is immediately visible, then auto-shrinks back
- Add --amber/--amber-border/--amber-glow CSS vars to all 4 theme blocks:
dark=#f59e0b (bright), light=#b45309 (deep, 4:1 contrast on light bg)
Fixes local-on/tools-toggle/backend-hint being nearly invisible in light mode
- Rename "Backend" ctx-section to "Role" (matches the role-cycle toggle)
- Update backend-toggle title from stale "primary backend" to "Active role"
- Capitalize distill buttons (Short/Mid/Long/All) to match Memory layer style
- Improve all ctx-panel button titles for clarity
