/* BarrierZero — Website.
   Designregeln, die dieses Stylesheet einhält (und vorlebt):
   - Kontrast: alle Text/Hintergrund-Paare ≥ 6,6:1 (AA verlangt 4,5:1)
   - Fokus: durchgängig sichtbarer 3px-Indikator, nie outline:none ohne Ersatz
   - Zielgrößen: interaktive Elemente ≥ 24×24 px (WCAG 2.5.8)
   - Bewegung/Scrollen nur bei prefers-reduced-motion: no-preference
   - Reflow: einspaltig ab schmalen Viewports, kein horizontales Scrollen
   - Links im Fließtext sind unterstrichen (nicht nur farbig) */
