/* ===========================
   RESPONSIVE.CSS
   Mobile-first breakpoints:
   – xs  < 480px
   – sm  480 – 767px
   – md  768 – 1023px
   – lg  1024 – 1279px
   – xl  ≥ 1280px

   STRATEGY:
   • Mobile-first: defaults above target small screens.
   • Only layout/size properties are overridden here — colors, transitions,
     and animations live in style.css to avoid specificity fights.
   • All breakpoints use min-width so rules cascade up correctly.
   • Grid column counts use explicit repeat() for predictable rendering
     on older Android WebView versions.
