/* ===== v2026 · responsive ladder — phone-portrait → 4K TV =====
   Breakpoints:
     ≤ 480   phones portrait
     ≤ 640   phones landscape / phablets
     ≤ 900   small tablets / portrait iPad
     ≤ 1200  tablets / small laptops
     ≥ 2200  4K / large displays
     ≥ 3200  8K / ultra-wide tv
   Modifier media:
     (pointer: coarse)         touch devices — hide crosshair, native cursor
     (orientation: portrait)   portrait tweaks for tablets/phones
   Component-local @media (e.g. invader-hud at ≤ 640, desktop-bar at ≤ 640,
   p-era at ≤ 640) live next to the component so the file stays focused.

}

/* ---------- Small tablet / phone (≤ 900) — pill / drawer pattern ----------
   At ≤ 900 every narrow viewport (phone portrait → small iPad portrait)
   uses the same pill pattern: menu + layers collapse into small pills
   anchored under the top bar. Tap to expand a vertical drawer, tap an
   item to act + auto-collapse. The horizontal chip-row attempt was
   wrapping (9 missions + 5 layers) and sandwiching the panel into a
   sliver with no body room.
   The second media term catches large phones in LANDSCAPE: their width can
   exceed 900 (e.g. 932) but a touch device that short (≤500 tall) is a phone,
   not a laptop — so it gets the same pill UX. Big tablets in landscape
   (height > 500) stay on the desktop layout. */
