   Design system : navy profond + accent BLEU (du navy au bleu du logo),
   fonds clairs. Ce fichier complète les utilitaires Tailwind (chargés par
   page) avec les composants réutilisables, l'ancrage typographique et les
   micro-interactions (hover + apparition au scroll).

   Nuancier d'accent « brand » (identique à la config Tailwind des pages) :
     300 #93c5fd · 400 #60a5fa · 500 #3b82f6 (bleu du logo)
     600 #2563eb (boutons) · 700 #1d4ed8 (texte/liens) · 800 #1e40af
