/* ---------------------------------------------------------------------------
   WebRun blog — article/gallery styles ONLY.

   The blog no longer ships its own design system: /style.css owns :root, *, body,
   a, header, nav and footer, and the shared includes/header.php + includes/footer.php
   render the real site chrome. What lives here is the part that is genuinely
   blog-specific — the post gallery, the article body typography and the CardGroup
   component. Loaded after /style.css via $extra_css, so it layers on top.

   Naming: the page hero is .blog-hero, never .hero — /style.css owns .hero as the
   100vh two-column marketing hero, which would blow up an article index.
   --------------------------------------------------------------------------- */
