/*
 * Styling for the static pages in `public/` — /about and the topic pages (T61).
 *
 * `public/` is copied verbatim by Vite and never passes through it, so these pages cannot
 * import `src/styles/tokens.css`; the handful of colours below duplicate that ramp. That
 * duplication is deliberate and documented in CLAUDE.md — the alternative was a
 * `vite.config.js` with a second Rollup input, reversing the no-config decision.
 *
 * What changed with T61: there were five pages about to carry five copies of the same inline
 * block. One stylesheet is still one duplication of the ramp, but in one place instead of
 * five. **If a token changes in `src/styles/tokens.css`, change it here too.**
 *
 * The app itself does not use this file: every stylesheet it needs is imported by
 * `src/main.js`, which is also why the shell has a `<noscript>` style block of its own.
