   AFFICHAGE BUREAU (écrans larges, à partir de 900px)
   En dessous de 900px (téléphones, tablettes en portrait), rien ne change :
   toutes les règles ci-dessus restent la mise en page mobile intacte. Au-delà,
   on bascule la même appli (mêmes boutons, même DOM, aucun changement de JS)
   dans une mise en page bureau : nav latérale au lieu de la barre du bas, et
   les écrans Statistiques/Réglages passent sur deux colonnes pour profiter de
   la largeur.
