/* Anemos Technologies — feuille de style du site 2026
   Concept : « deux portes ». Les toitures vivent en lumière (blanc de toiture, ciel),
   les drones en bandes nuit (le bleu-noir des vidéos techniques Anemos, un orange signal).
   Détail propre au sujet : la « plaque signalétique » (caractéristiques en chiffres et unités). */
