- F1: "Sauvegarde locale" panel in Profil (both signed-out/signed-in states, positioned per UX cadrage), "Exporter mes données" calling DataExportUseCase.exportAll() then handing the file to the system share sheet, with the exact UX success/error snackbars. - F2: "Importer des données" picks a file, previews it, then confirms with the exact UX dialogs: simplified single-choice when there is no local data yet, Fusionner/Remplacer tout (with a destructive second confirmation) otherwise. All typed LocalBackupValidationError cases are mapped to their dedicated dialog copy, including the active workout session block.
