/* ===== MODE CONCENTRATION ====================================================
   Certains écrans travaillent en largeur — le tableau de réorganisation en
   premier. Les deux niveaux de navigation s'effacent alors ensemble : la
   barre latérale et le rail d'administration. On ne les supprime pas, on les
   replie, et un bouton les ramène.

   Le repli se fait à la largeur, pas en `display: none` : c'est ce qui permet
   au contenu de s'étaler d'un mouvement continu plutôt que de sauter.

   Sur mobile, la barre latérale est déjà hors champ derrière son bouton : le
   mode n'a rien à y replier, et s'y appliquer casserait le tiroir.
