   FIHARY — PAGE DÉMONSTRATION : onglets verticaux auto-advance (08/09/2026)
   - Rail vertical à gauche : carrousel d'onglets — la piste glisse (friction)
     pour toujours garder le rôle actif au centre de la fenêtre
   - Barre de progression sur l'onglet actif (temps restant avant le slide suivant)
   - Filmstrip vertical à droite : les écrans défilent avec un easing doux
   - Panneau d'explication synchronisé : nom du rôle + « il voit » + « il peut »
   - Pause au survol / focus / clic · reprise automatique · reduced-motion respecté
   Règles brand : Inter exclusif · radius ≤ 12px · zéro ombre sur cartes ·
                  Teal = argent entrant · Purple = premium uniquement.
