- 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).
