/* ══════════════════════════════════════════════════════════════════════
   ADAPTIVE LAYOUT STYLESHEET  v3.0 — Compose Model
   ══════════════════════════════════════════════════════════════════════
   Complete rewrite: CSS-first responsive design using @media queries.
   No longer depends on JS data-attributes for layout.

   FIXES: FOUC — layout now applies instantly via media queries,
   no waiting for JavaScript DOMContentLoaded.

   SIZE CLASSES (Google Compose Window Size Classes):
     compact  → <600px  (phones portrait)
     medium   → 600–839px (tablets portrait, landscape phones)
     expanded → 840–1199px (tablets landscape)
     large+   → ≥1200px (desktop — default)

   LOAD ORDER:
     1. ds.css        (tokens + components)
     2. adaptive.css   (THIS FILE — responsive)
