   Qualithermy — feuille de style du site
   Concept : « eau & flamme ». La dualité froid/chaud du logo devient une
   échelle thermique (bleu → orange) utilisée avec parcimonie. Fond clair et
   aéré, bandeaux marine pour les moments décisifs, orange réservé aux actions.
   Thème clair unique, assumé pour respecter les couleurs du logo.
