/* EyeRest design tokens, vendored from qte77/qte77/brand/DESIGN.md — this dashboard is a
   plain, zero-build static page (see docs/plans/0002-readiness-dashboard.md), so the tokens are
   hand-copied here as plain CSS custom properties rather than consumed from the published
   @qte77/ui-theme npm package (Tailwind v4 `@theme` tokens, not usable without a build step) or
   authenticated against GitHub Packages. Same vendoring approach paperverse/ui/src/theme.css
   already uses for the same brand source. System font stack only (no self-hosted Inter/
   JetBrains Mono webfonts) — a reasonable v1 scope, see the plan's "Open items" section. No
   manual theme toggle: this page tracks the OS `prefers-color-scheme` only. */
