/* ===================================================================
   Coding "My Rewards" (.cjr-*)
   The adult coding rewards VIEW (the approved design): a developer-styled header with a
   "badges unlocked" summary card, a Badges grid (earned + not-yet-earned), and a Certificates grid
   (gold earned cards / dashed locked cards). Badges + a completion certificate only -- no
   collectibles. Used ONLY for the !IsKidShell branch of RewardCollection.razor; the kid trophy case
   (.coll-page-kid) is untouched. All color/elevation lives on the --cjr-* token layer (light :root +
   the dark body.dark-mode block below) so component rules stay token-driven (no stray hex) and dark
   mode re-themes by re-pointing tokens; the dark-mode wiring guard (KidsDarkModeCssWiringTests) scans
   this file for the body.dark-mode gate and the absence of an OS color-scheme media query. */
