/* =====================================================================
   blog.css: styles for the worker-rendered blog pages (listing, category, article, 404, preview).
   Copied by scripts/build-site.mjs to public/assets/blog.css and linked from every blog page
   after the site's own base.css / site.css / v2.css, so it reuses their tokens
   (--ink, --body, --muted, --line, --brand, --display, --sans, --header-h) and only adds what
   the static site has no component for. Tailwind's CDN preflight resets lists, links and
   heading margins, so long-form text rules below set them explicitly.
