/* ============================================================
   BLOG.CSS
   Page-specific styles for blog.php (article layout).
   The hero (background image + title) uses the shared .event-hero
   styles from common_specific.css.
   Loaded AFTER common_specific.css, so rules here override the
   shared detail-page styles (resources, etc.) for this page only.
   The .author-strip box is NOT styled here: it comes unchanged
   from common_specific.css.
