   1. CSS VARIABLES (Design Tokens)
   --------------------------------------------
   Token system per docs/uiux-visual-spec.md:
   - brand green is reserved for brand moments, primary actions,
     key links and selected states — never large surfaces.
   - neutral surfaces + ink carry the page.
   - legacy var names (--green-*, --gray-*, --text-*) are kept as
     aliases so existing pages continue to resolve.
