  HEADER - RunArt Base Theme (Blanco y Rojo)
  UI/UX Improvements 2025-11:
    - Spacing nav desktop 2rem→3rem, tablet 1rem→1.5rem
    - Gap menú desktop 0.5rem→0.75rem; tablet 0.25rem→0.5rem
    - Active state con background rgba(195,0,0,.15) + font-weight 600
    - Focus-visible accesible en logo, nav links y language switcher
    - Language switcher mantiene fixes Chrome en responsive.overrides.css
