/* ============================================================
   BLOG.CSS — styles specific to blog.html / blog-post.php
   Requires base.css to be loaded first. Reuses base.css's tokens
   (--plum-dark/--brass/--ivory/--charcoal/--grey-plum/--line) and the
   site's existing card/button conventions rather than introducing a
   new visual language.
