/* ── byte design tokens ──
   The one source of colour, font and shadow values for the web app (index.html) and the world map
   (map.html, a sandboxed iframe, which links this same file). Neutrals and the indigo accent come
   from the enginar family palette (iz: src/constants/theme.ts); the rest is derived so every
   text/background pair passes WCAG AA. Values and contrast ratios: docs/DESIGN_TOKENS.md.
   Served from web/public: by Vite in dev, by the backend's static files in production. */
