/* ═══════════════════════════════════════════════════════════════════════
   Composant partagé — Fil d'Ariane élève
   Utilisé par js/breadcrumb.js. Barre sticky positionnée juste sous la
   navbar fixe (top: 50px — voir `body:has(.navbar) { padding-top: 50px }`
   dans styles.css). Toutes les références aux tokens globaux de styles.css
   (--border, --muted, --font-display, --color-brand-navy,
   --color-brand-gold, ...) ont une valeur de repli : le composant s'affiche
   correctement même sur une page qui ne charge pas styles.css.
