/* ==========================================================================
   GRIDIRON — css/gridiron-challenges.css
   The CHALLENGES screen (js/gridiron-challenges.js): the tag + crew row, the
   DAILY and WEEKLY challenge cards, and the leaderboard under each.

   Every value is a var(--token) from css/gridiron-tokens.css. None of
   COMBINE's hexes and none of its token NAMES (--cb-accent, --cb-grade-a …)
   appear here — this game themes through its own file.

   One shape has no COMBINE counterpart: a challenge here names a UNIT
   (offense / defense / special teams / the whole team), so every card
   carries a unit chip tinted with that unit's own colour off data.UNITS.
