amosblomqvist 9b75b4f785 ui: consistency sweep — the 1ch rail geometry, Submit thinking, no auto-caps
Owner round 4 (2026-10-05):

- THE RAIL IS THE MISSING CHARACTER: rail + padding = exactly 1ch of
  the mono heading font. 'YOUR THINKING' (13ch) + rail == 'AGENT
  THINKING' (14ch) flush — the chevrons line up vertically, no fixed
  columns. The YOU heading joins the rail (label inside, like the
  thinking rows) — one quote geometry everywhere.
- HEADING REGISTER: YOUR THINKING / AGENT THINKING / YOU all use the
  card eyebrows' small mono caps (text-xs = the 11px rung, font-medium
  uppercase tracking-wide) — the app chrome is JetBrains Mono.
- SUBMIT THINKING: the practice button is now literally the question
  dock's Button (h-9, px-3.5) in one p-1 row with the hint left
  ('↵ submits · ⇧↵ newline') — the keyboard hints are back. Corner
  radii concentric in both docks: shell 16 − 6 = field 10 − 4 = button 6
  (rounded-[10px] fields, rounded-[6px] buttons — the old rounded-xl/12
  was the 'too large' culprit).
- MODEL NAMES: prettyModel no longer auto-capitalizes — names render
  exactly as their providers write them ('glm 5.3 flash').
- Quiz explanations pulled closer (mt-3 → mt-2).

/** The unified user-thinking row (owner round, 2026-10-05): ONE visual
* language for every surface where the learner's own thinking renders —
* practice thinking traces, the reading channel lifted above the answered
* card, the quiz answer's thinking inside its container. It arrives
* COLLAPSED as a trigger row in the exact register of the agent's
* reasoning rows (muted label + chevron + hover affordance); expanding
* opens the quote block — rail, 50% opacity, italics. The italics + the
* half-opacity text are the inner-voice signature; the rail marks it as
* learner material. No shell, no border: document material, full width.
*
* The glance-level law (owner): user thinking = rail + 50% italic;
* agent thinking = no rail. */
