/* Extracted verbatim from the homepage's inline <style> (landing-page/index.html, lines
   51-586, checked at commit f5823c46) — the homepage embeds its whole stylesheet inline and
   has no external CSS file to link to, so this file exists purely for the blog: /blog pages
   link to it instead of re-embedding ~540 lines of CSS in every rendered article. The
   BLOG-ONLY section below extends it with classes the homepage doesn't need. Keep the
   COPIED FROM HOMEPAGE section byte-for-byte in sync if the homepage's own <style> changes. */
