/* Weekly Puzzle board + side column. Shared by rewards.html (the real tab,
   logic in rewards-puzzle.js) and manage-puzzle.html (the admin preview), so
   the preview is the player view, not a lookalike.
   Since 2026-09-28 it wears the Rewards "stage" look (Path hero, Wheelspin):
   an always-dark card with a glow, Geist type, a big white title, chips,
   glass tiles and a full-width action bar. The stage is dark in BOTH themes,
   so colours in here are literal, not theme tokens. */
