/* SS Construction Isolation
   Concept : « coupe technique ». Un héros bleu nuit avec la coupe animée d'un entretoit,
   puis des feuilles blanc neige où des dessins de détail racontent chaque service.
   Texte aligné à gauche, 62 caractères max. Une seule animation orchestrée : l'isolant
   qui monte jusqu'à R-50. Le reste est calme.
   Un seul thème, voulu : l'identité de la marque (fond clair, bandes bleu nuit). */
