/* BigPool UI refresh — challenges. Uses the shared design language from app.css (Oct 2026).
   Covers: the challenge card (also shown in the lobby), /challenges, /challenges/new,
   and the shared /challenge/:id invite (plus its "seat taken" state).
   Card internals use :where() so the lobby's phone "challenge bar" rules in app.css
   (.home-challenges …) keep winning on the home page. */
