/* Riddle Up — shared puzzle game screen.
   Shared by every puzzle mode (Classic "What Am I?", Rebus, Logic,
   Detective & Lateral Thinking - see PuzzleController@play); the mode
   only changes which riddle pool is played, not this screen. Mobile-
   first, centered single-column game container. Uses the `--surface-*`
   dark-theme-safe tokens defined in ../site.css (loaded sitewide).
   Loaded only on puzzle play pages via \Assets::add. */
