/* ============================================================
   ALASKA FROZEN — iwocaPay credit banner component
   File: css/iwocapay-banner.css
   Namespace: .iwp*  (no collisions with brand.css)

   Load AFTER css/brand.css so the design tokens resolve:
     <link rel="stylesheet" href="/css/iwocapay-banner.css?v=1">

   Tokens are this site's own: --accent, --ink, --line, --muted,
   --paper-2, --font. (--ice exists only in wow.css, which the
   homepage alone loads, so its fallback is the same value.)

   Variants
     .iwp.iwp--wide       full-bleed light band, sits BETWEEN sections
                          (provides its own inner wrapper — do NOT nest in .container)
     .iwp.iwp--contained  sits INSIDE an existing .container
     .iwp.iwp--rail       optional 160x600 skyscraper for the category sidebar
                          (auto-hides below 1000px)

   Artwork tiers — the artwork is never stretched or upscaled past its
   intrinsic width, because the baked-in offer text must stay legible:
     < 700px            970x250  (billboard, fills the column)
     700 - 999px        728x90   (leaderboard, near native size)
     1000 - 1399px      970x250  (billboard, near native size)
     >= 1400px          1920x90  (full strip — .iwp--wide only)
