- THE 3CH RAIL: 'AGENT’S THINKING' (16ch, flush) − 'YOUR THINKING' (13ch)
  = 3ch of mono — the rail widens to 3ch (border + padding), keeping the
  chevrons aligned while giving the quote room to breathe (the 1ch rail
  read cramped). YOU row follows.
- THE STANDARD CHORD everywhere: Enter submits, Shift+Enter is a
  newline, ⌘/Ctrl+Enter works too — the teaching thinking field drops
  the ⌘-only Gmail convention; the hint reads '↵ submits · ⇧↵ newline'
  in both docks, shown in text mode too (it Enter-submits as well).
- The transcript-end optimistic placeholder joins the register: small
  mono caps THINKING… (was text-sm sentence case).
- Model names keep their dashes: prettyModel renders 'glm-5.3-flash'
  exactly as written (no auto-caps, no dash→space join).
