/* ============================================================
   franco-media.com - layout A, the rail zones and the banner bands.
   TASK-N23, 05-10-2026. Rulings CT (layout A, one rail plus in-content
   bands, supersedes the three-column layout B) and CS (contain, never
   crop; the five build decisions). Design source: D03.

   The page grids are NOT redefined here: content 820 px and the 340 px
   rail are the existing .split (shared-components.css) and .asplit
   (article.css) grids, unchanged. This file styles only what the zones
   print: the banner image, the "Publicité" caption, the
   Catégories widget, the band, and the gated hub page.

   TASK-N23b, 05-10-2026 (ruling CV, Fabrice's correction): no card around a
   banner. Each banner is the bare image, edge to edge across its zone's width
   (the rail, or one band column), whole, at its natural ratio, nothing
   cropped. One small "Publicité" caption per zone sits above the banner
   stack. No carousel, no slideshow, no premium badge.

   Existing tokens only (AQ2): no hex value is written in this file.
