   Capital Hacks — site styles
   Colors and type come from the Capital Hacks Logo Kit
   (web/css/capital-hacks-tokens.css), built on the Carlsen
   Center identity standards. Rules worth remembering:
   - Teal is for marks, lines, focus rings and dark surfaces,
     never running text on white (fails contrast).
   - Never set purple type on the green.
