/* =====================================================
   /blog listing (homepage-matching design, live since 2026-10-04)
   Used only by app/Views/blog/listing.php.

   Loaded AFTER home.css: reuses the homepage's tokens and building
   blocks (.hv1 colours, .hv1-hero, .hv1-head, .hv1-cta ...), so changing
   those in home.css changes this page too, on purpose. This file only
   adds the .bl-* parts: breadcrumb, featured post over the hero edge,
   post cards. --c is the post topic's colour, set inline per card.
