   1. POLICES & VARIABLES
   - Cormorant Garamond : police "display" élégante, utilisée pour tous les
     titres (reprend l'esprit serif fin de la brochure NAE Live).
   - Jost : police utilitaire sans-serif, pour la navigation, les labels,
     les boutons et le formulaire — lisible et discrète.
   - Alex Brush : police script, réservée exclusivement au logotype
     "Live" (comme dans la brochure) — jamais utilisée ailleurs, pour que
     ce geste reste rare et reconnaissable.
