   Loaded ONLY on /blog/index.php and /blog/post.php, on top of assets/style.css
   (which provides the --bg / --gold / --line tokens, the header/footer chrome,
   and the base .btn). This layer adds an editorial, magazine-grade reading feel:
   an elegant serif display face for headings, a comfortable ~68ch measure,
   generous vertical rhythm, and refined cards. CLASS-BASED ONLY — the strict CSP
   forbids inline styles, so every rule here is reusable and self-contained.
