   Mobile-First-Strategie:
   Die Basis in style.css ist bewusst weitgehend fluide (clamp(),
   grid auto-fit). Hier werden nur die Stellen überschrieben, an
   denen es echte Layout-Wechsel braucht.

   Breakpoints:
   • <= 768px   Mobile (Hamburger-Menü, gestapelt)
   • 769-1023   Tablet
   • 1024-1279  kleine Desktops
   • >= 1280    große Desktops (= --container-max)
