/* OrbeviaGroup — feuille de style
   Direction : interface technique et futuriste aux couleurs d'Orbevia (nuit, crème, laiton).
   Règle de couleur : le laiton porte l'identité ; UNE couleur signal (ultraviolet) est réservée
   à ce qui se clique. Formes : coins coupés (.cut), étiquettes en police mono, grille de points.
   Mise en page : en-tête collant ; récit plein écran dont la scène reste fixe pendant que le défilement
   passe d'un tableau à l'autre (story.js) ; puis manifeste qui s'allume au défilement, cartes de marques,
   contact avec panneau de données, et pied de page au nom du groupe en très grand. */
