/* ClinkRate content pages (guides + scorecard).
 *
 * Standalone stylesheet for the static SEO pages — these are plain HTML and
 * never load the React bundle or Tailwind. Tokens are copied from
 * frontend/tailwind.config.ts + frontend/src/index.css so the pages match the
 * app exactly; if the app's palette changes, mirror it here.
 *
 * Versioned filename (style.v1.css) on purpose: firebase.json caches *.css as
 * `immutable, max-age=31536000`. Bump to v2 (and update the <link> in every
 * page) when editing, otherwise returning visitors keep the old file.
