   BRIKZ — habillage. Mobile-first : une seule colonne, tout au pouce, rien qui
   depasse sous l'encoche. Le canvas s'etire, les overlays se superposent.
   Le bloc RTL en bas du fichier suffit a l'arabe : les rangees s'inversent,
   les libelles s'alignent a droite, le canvas ne bouge pas (le jeu se lit de
   la meme facon dans les deux sens).
