   nur bei Tastatur-Fokus sichtbar, Ziel: #content.

   Nutzt das etablierte "visually hidden until focus"-Muster
   (wie .sr-only in base.css) statt einer negativen top-Position:
   robuster gegenüber dem sticky-Positionierungskontext von
   .voma-header, der bei top:-4rem zu einem dauerhaft sichtbaren
   Skip-Link führte (Befund Staging-Review, 01.07.2026).
