/*
 * The published site's stylesheet — copied verbatim into site/ by
 * scripts/site/build.ts.
 *
 * Deliberately hand-written rather than extracted from apps/web: the app's CSS
 * is CSS Modules compiled by Next, and pulling it through a bundler just to
 * publish eight kilobytes of static pages would make the site's build depend
 * on the app's. The tokens below are copied from apps/web/app/globals.css and
 * are the contract between the two — if the brand moves, they move together.
 *
 * Light only, matching the product. The fonts are the repo's own self-hosted
 * woff2 files (see the note in apps/web/app/layout.tsx about why they are not
 * fetched from a CDN at build time).
