   Karim Akh el Arab — Feuille de style
   Ambiance : galerie d'art contemporaine, chaleureuse et
   sophistiquée. Le caractère vient du contraste (sombre/crème),
   de la typographie et du relief — pas d'une surcharge de couleurs.
   Palette volontairement neutre + un seul accent bronze, pour
   servir aussi bien le figuratif que l'abstrait.

   Pour modifier les couleurs/polices : voir :root ci-dessous.
