   wede — website design system
   Mirrors the "Wede Midnight" theme shipped in the app (src/index.css):
   warm indigo-tinted neutrals, electric-indigo accent, coral spark from the
   logo slash. Fonts are vendored locally (no Google Fonts, no runtime CDN) —
   the same sovereignty rule the product itself follows.
