/* Loriginary v4.0 UX21 production overrides
   Primary navigation contract:
   - every main-menu label uses the same font, size, weight, height, and visual treatment
   - each button is only as wide as its own label requires
   - labels stay on one line on desktop
   - very short entries such as UHU, Help, and FAQ are intentionally allowed to be narrow
   - horizontal scrolling remains only as an emergency fallback on smaller windows */
