/*
 * The blog surface's only stylesheet, shared by /blog and every article.
 *
 * These pages are plain static documents under public/, copied to dist/ verbatim and served
 * by their own URL, so they carry no script, no bundle and no React: the crawler and the
 * reader get the same bytes, and nothing can overwrite the title or description after load.
 * That is the whole point of the surface, so keep it script-free.
 *
 * `.css` is one of the extensions vercel.json's SPA rewrite excludes, so this file is served
 * from the filesystem and never rewritten to the app shell.
 *
 * System fonts only: the app's web fonts are bundled assets with hashed names, and a static
 * page outside the bundle cannot name one that survives a rebuild.
