/* ---------------------------------------------------------------------------
   Blog styles - shared by blog.php (index) and blog_post.php (article).

   Two things about the surrounding site shape everything below:

   1. style.css sets a global `a { font-size:15px; letter-spacing:3px }`, which
      is fine for nav but wrecks links inside running prose. Everything under
      .blog-scope resets link typography back to inherit.
   2. header.php's mobile script bolts .mobile-text-large / .mobile-link-large
      (20-22px, grey, display:block, !important) onto paragraphs and links on
      phones. Blog pages opt out via .no-mobile-restyle; the resets near the
      bottom of this file are a second line of defence if that script changes.
