/* ============================================================
   CURIOUS FOUNDATION (plan item 2A)
   Design tokens + one shared button / card / pill system.
   Loaded on visitor pages after style.css (so new components win)
   and imported first by dashboard-main.css.

   Per-site branding still applies at runtime via v2-config.js —
   these tokens are the defaults underneath it.
