/* ==========================================================================
   Blog v3 — thin overlay on top of kb-v3.css
   Reuse kb-v3 class vocabulary for layout/cards; this file adds only the
   blog-specific bits: byline/date meta row, featured-post treatment,
   pagination controls, and migrated-content helpers (video embeds, captions,
   float alignment). All colors come from the shared --et-* design tokens.

   Layout escape + page-header artifact (mirrors kb-v3 §1, keyed to data-blog)
   Blog pages render no page-header; the base layout still emits an empty
   .page-header-v3 band, and .main-content-v3 keeps its gutter — both must be
   neutralized here or every blog page opens with ~200px of dead space and
   the dark hero bands render inset instead of full-bleed.
