/* ============================================================================
   The composer — the question box (Oct 2026)
   ----------------------------------------------------------------------------
   One card. The question on top, a quiet toolbar below; the orange Send is the
   only filled control. Three states, each carried by ONE motion or ONE row:

     before  → the card at rest; context mode is a chip, shortcuts sit under it
     during  → a hairline travels the top edge and a ring circles Stop; the box
               stays live (S10 steering) — nothing in it repeats the answer's
               work line (that fact lives once, in the Living Answer)
     after   → the turn's receipt row on top of the card (verdict · time ·
               tokens · cost · trust record) until the next keystroke

   Theme tokens only; reduced motion keeps every state and removes the travel.
