/* Conversation practice (round 4, lane L4): setup, the chat, the feedback card. Kit tokens only (styles/tokens.css,
   motion.css). Who is who (DESIGN.md Colors): the partner's bubble is ink on surface-2; his own is surface with a thin
   accent edge. Accent marks him and now: his bubble's edge, a correction of what he wrote, focus. Motion: a reply rises
   in, its correction's dotted underline draws once the reply is complete, the feedback sections unfold one after
   another (motion.js reveal). Every distance is × --move, so reduced motion keeps only short fades. */
