amosblomqvist b770834f29 ui: the rail GROUPS — the thinking label sits inside the rail
Owner correction (2026-10-05): the collapsed trigger row carried no rail,
so ownership was only visible once expanded. The rail now wraps the whole
block — label (trigger) and, on expand, the italic 50% text — so the
quote reads as one object and WHICH thinking belongs to whom is clear
from the rail alone, collapsed or expanded. Same shape as the user text
('You') row.

/** 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. */
