/* Fujian Dashan Paper — feuille unique.
   La palette sort des photos de l'usine : le vert du logo 大山纸业, le bleu du
   ciel de Quanzhou, le blanc du bardage. Clair, frais, accueillant.
   Le fond industriel (rouleaux + bande qui defile) est dessine en SVG inline,
   pas en image : il suit le theme et ne coute rien a charger. */
