/* Shared styles for every page under /blog/ — extracted so the CSS lives in exactly one place
   instead of being copy-pasted into every generated post (see scripts/build-blog.mjs). Loaded
   via <link>, not inlined, specifically so it's cacheable across posts instead of re-downloaded
   (and re-parsed) per page.

   Contains the generic page shell (reset, header, typography, footer) *and* the small set of
   reusable article widgets (game tiles, mode cards, post cards) — future posts should reach for
   these existing classes before inventing new ones; see POST_IDEAS.md.

   Not shared with tos.html/privacy.html — those are two stable, rarely-touched pages, not a
   growing set, so the duplication cost there is low; revisit only if that changes. */
