/* ===== 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.
