   Layer over base.css. Nothing here redefines a base token; every
   colour, font and radius comes from the design system so the
   Academy reads as part of the site, not a bolt-on.

   Page types, all sharing .ac-hero:
     /learn/                      the Learn hub
     /learn/academy/              academy hub, three tier cards
