/* =========================================================================
   LUTUMAMA PHOTOGRAPHY — feuille de style
   Principe : la page est un mur blanc de galerie. Les photos parlent, le
   texte se tait. Une seule famille de caracteres (Garamond), pas de
   capitales espacees, pas de couleur d'accent : le noir et le blanc, et les
   couleurs des photographies.
   Les couvertures de mariage s'affichent entieres, a leur format d'origine
   (3:2) : aucun visage coupe.
