/* ---------- Anime Navbar — liquid glass + mascota ----------
   Portado de un componente shadcn/framer-motion ("AnimeNavBar") a HTML/CSS/JS
   vanilla — el sitio no usa React (ver pagina-completa/assets/volumetric-hero.css
   para el mismo criterio de port). Material "Liquid Glass" tomado de
   liquid-glass-preview/index.html (blur+saturate, highlight que sigue el
   cursor) con los tokens de marca de ARV (--accent/--accent-glow/--ease) en
   vez de la paleta genérica azul/morada del demo original. Reemplaza a
   .site-head / .nav / .nav-toggle (esas reglas se dejan sin usar en
   styles.css como red de seguridad mientras Axel confirma el cambio). */
