   EASY ACADEMY — LECTURE DES FORMATIONS ÉCRITES (Phase 13)
   Le lecteur de diapositives est sombre et immersif ; la lecture longue
   demande l'inverse : fond clair, colonne étroite, typographie ample.
   Cette feuille ne s'applique donc qu'au corps de lecture, la colonne
   latérale du programme reste celle du lecteur (player.css).
