/* Stylesheet for the prerendered /blog pages (scripts/build-blog.ts). These
   pages are static HTML outside the Vite/React bundle, so this file is
   hand-authored plain CSS rather than Tailwind output — it avoids depending
   on a build-time-hashed asset name and keeps the pages framework-free.
   System font stack only: no extra font requests, matches the "fast loading"
   goal for pages that exist to rank. */
