/* ============================================================
   Respeak Trust Center
   Palette lifted verbatim from the product's design tokens
   (document_expert → 01_frontend/src/assets/tokens.css) so this
   site reads as the same system. Keep the two in sync by hand:
   this repo deliberately has no build step and no dependency on
   the app, so a token change there is a manual copy here.

   No webfonts, no external requests, no JavaScript — a trust
   center that phones out to a CDN argues against itself, and a
   zero-JS page lets the CSP below stay maximally strict.
