/* ==========================================================================
   AMBytz — editorial front-page layer.
   Loaded after site.css, only on the front page and the archive.

   These are standard newspaper layout conventions — a sparse centred masthead,
   a topic strip, a dark full-bleed lead, a kicker/headline/byline card, a story
   river, and ruled section blocks. Brand tokens, type and content stay AMBytz's
   own; only the editorial grammar is modelled on how news front pages work.

   No photography exists for this outlet, so every image slot degrades to a
   typographic "record" panel rather than a placeholder or a stock photo. If real
   art arrives, drop it into .lead-art / .card-art and the layout absorbs it.
