ui: the chat comeback — side-based authorship, restored quotes, tucked whys
Blockquotes: the callout override had displaced Streamdown's own styled blockquote component, so plain quotes rendered as bare unstyled text since that commit. The pass-through branch now restores Streamdown's verbatim classes (border-l-4, muted italic). Explanations tucked for ALL questions (owner): the prediction's Why / Hide-why toggle is universal — every quiz answered card sits its explanation behind the same collapsed button. Same pattern, one law. The thinking row's rhythm: my-1 -> my-3. The 4px margin hugged the options on non-graded answered cards (owner report); 12px matches the card's mt-2/mt-3 spacing grammar everywhere the row renders. Side-based authorship (owner round, 2026-10-07): the document shape blurred user into agent — three left-rail idioms (user text, user thinking, quoted prose) collided once quotes rendered. User rows go RIGHT: 'You' messages and practice thinking cards hug the right edge at 85% width with the rail mirrored (border-r), text still reading left-to-right. In-card thinking (inside the answered card, the agent's context) stays left. Transcript thinking rows arrive EXPANDED — the thinking was clearly sent. Cmd+T (toggle-user-thinking, chat scope, cheat-sheet row) sets every user-thinking row to one state via a module store: explicit sets stomp individual toggles, late mounts honor the last set (the state initializer reads the store, so static render reflects it too).
