/* ==========================================================================
   Post — /blog/<slug>/

   Loaded after blog.css, which already carries the band ground (.gw-blog__bg),
   the 1264 measure (.gw-blog__wrap), the label row, the byline, the image
   slot, the promo card, the pill and the index card (used again for related
   articles). This sheet adds only what a post has and the index does not: the
   breadcrumb, the two-column band, the article measure and its typography,
   the sticky sidebar, the author box.

   Structure follows the Kissflow article (breadcrumb → image-left band → body
   beside a sticky contents list → related). Every value is this theme's.
