/* AD Microfusion : feuille de style.
   Même principe que les sites de Vanessa (aéré, sections, téléphone d'abord),
   aux couleurs du logo : noir olive #1f2315 et turquoise #1bb2a2.
   Le turquoise du logo est trop clair pour du texte sur fond clair : on y
   utilise --turquoise-fonce (contraste suffisant), et sur les boutons
   turquoise le texte est noir, pas blanc. */
