   Feuille de style unique. Aucun framework, aucun build : ce fichier se dépose
   tel quel chez Hostinger.

   Charte : le bleu du logo (maison, lettrage) porte la confiance technique ;
   le cuivre de la flamme est l'accent d'action (boutons, repères). Le fond
   reste clair et aéré ; les sections sombres (marine) servent aux moments
   forts : le hero, l'espace client, l'appel à l'action final.
