/* Weekly Challenges — "Classic Steam client", same look as the leaderboard.
   The page window, title bar, heading and foot come from leaderboard-classic.css
   (body carries both lb-classic and chal-classic); this file styles only what
   challenges.js renders: the week strip and the four challenge panels. Every
   rule is scoped under body.chal-classic and overrides challenges.css (still
   loaded). Square corners. No emoji. */
