   fromscratch — public blog (backend-rendered, app/templates/blog/).
   Served at /blog-static/blog.css?v=<hash> (immutable). Loaded AFTER the site
   CSS (frontend chrome.json head: tokens + Tailwind + site chrome), so it only
   reads the Mat role tokens (--ui-*) and color-mix() tints: both themes
   (html[data-theme=dark|light], set before paint by the inline script copied
   from frontend/index.html) are right without a single hex value here.
   Sections: base · list pages · cards · article · prose · content pages ·
