ui: conclude card — quiz-chip outcomes, verdict-first; YOUR THINKING / AGENT THINKING

Owner round 3 (2026-10-05):

- CONCLUDE CARD: the stacked same-weight headings are gone. Plain
  'Concluded' eyebrow + the outcome in the quiz cards' EXACT chip
  register. Colors per outcome: solved green (the 'correct' twin),
  solvedWithHints amber (succeeded with cost), surrendered red (the
  problem won), movedOn muted (the agent's call, not a verdict against
  the learner). Verdict as plain 50% prose under the heading — the
  'Verdict:' label is gone — then a divider, then the labeled model
  solution.
- ALL-CAPS: 'YOUR THINKING' and 'AGENT THINKING' — display strings only
  (the model-facing marker label stays sentence-case). The two rows are
  equal-length over the shared rail, so the chevrons align vertically.
  Dock field labels match.
