   CasesTrain — shared design layer
   -----------------------------------------------------------------------------
   Every game carries its own accent from the hub card into play. The accent is
   an RGB triplet in --ac (plus a lighter --ac-hi and deeper --ac-lo) so both the
   Tailwind brand-* utilities and hand-written CSS can use it with any opacity:
       color: rgb(var(--ac));            background: rgb(var(--ac) / 0.12);
   --ac-fg is the text colour that sits on a solid accent fill.
   main.js stamps body[data-game]; Habitat Builder also stamps body[data-terrain].
