/* ═══════════════════════════════════════════════════════════════════
   Q&A — the board, a question, and the composer.

   Tokens, sections, buttons and cards come from signal.css. What is here
   is the furniture a question board needs and the system does not have:
   a vote column, an answer with an accepted state, inline comments, and
   a composer that works with a thumb.
