   BrickCrunch /guides static-post stylesheet.
   Used by /guides/post-template.html and every published post.
   Deliberately self-contained and UNHASHED so published posts
   never break when the React bundle is rebuilt. Mirrors the
   core look of src/index.css — if you restyle the site, update
   the shared tokens here too.
