   CORBEAU - feuille de style
   Univers sombre et editorial, pense comme un catalogue d'exposition :
   fond noir, texte blanc casse, un seul accent or par petites touches.
   Signature graphique : des reperes de cadrage en filet fin qui
   apparaissent aux quatre coins des visuels au survol, comme les
   marques d'imposition d'un tirage papier.
   Mobile first : tout ce qui suit vaut pour le petit ecran, les
   media queries ne font qu'elargir.
