/* ─────────────────────────────────────────────────────────────
   Foldable layouts — tuned for the Galaxy Z Fold 8, shared by every page.
   Loaded after each page's own styles, so these rules win.

   Cover screen: 5.5", 1248 × 1972 px, 10:16. In a browser that is a short
   "passport" viewport of roughly 420–480 × 560–700 CSS px. It is much less tall
   than a normal phone, so it is detected by aspect ratio, not width alone.

   Inner screen: 7.6", 2448 × 1848 px, 4:3, and wider than tall when unfolded.
   That is roughly 820–950 × 560–720 CSS px, a small touch landscape. Without
   these rules it would get the hamburger, single-column mobile layout.

   Also covers the Fold 8 Ultra (21:9 cover, 10:9 inner), rotated inner screens,
   and the half-folded postures, via the Viewport Segments API where supported.
