   Visionneuse de carte — commune à Cézanne et L'Italien.

   Le client ne voulait plus d'ouverture dans un nouvel onglet : la carte
   s'affiche désormais dans la page. Les pages du BAT d'impression sont
   rendues en WebP, donc aucun lecteur PDF n'est chargé — la fenêtre s'ouvre
   instantanément et fonctionne partout, y compris sur mobile.

   Chaque site injecte sa propre palette via les variables --mv-* ; tout le
   reste est commun.
