/* ══════════════════════════════════════════════════════════════════
   BLOG INDEX, v3
   Direction: compact intro, one large full width featured banner, then a
   visual article grid that dominates the page. The grid is the content.

   Loads after home-v2.css and service-v2.css, which supply tokens, .wrap,
   .sig, .ovl, .btn and the section background classes.

   Every article has a real 1200x628 featured image, so there are no CSS
   editorial covers here and no stock imagery. Square editorial framing,
   thin rules, no shadows, no gradients, no floating cards.

/* home-v2.css already gives a section 140px of top padding to clear the fixed
   header, and .bintro was adding its own on top of that, so the label sat
   155px below a 71px header. The section pad is zeroed here and .bintro owns
   the whole distance, which keeps it to one number instead of two stacked. */
