/*
  Deprecated/removed: notification_service.dart

  This legacy notification service has been intentionally removed.
  The app now uses a minimal scheduler in:
    services/simple_notification_service.dart

  All retry/snooze/database-tracking logic has been dropped to keep things simple.
  This file is left empty to ensure any lingering references fail at compile time,
  prompting migration to the new SimpleNotificationService.
