/* ==========================================================================
   Chipd design system
   --------------------------------------------------------------------------
   Hand-rolled CSS, deliberately not Tailwind. The Play CDN compiled styles at
   runtime, which is why the CSP needed 'unsafe-eval'; owning the stylesheet
   lets that exception go away and removes a render-blocking round trip.

   Two token layers:
     1. Raw palette  — never changes, never referenced by components.
     2. Semantic     — flips per theme. Components only ever use these.
