// ============================================================
//  main.dart — App Recolecta (corregido)
//  Cambios aplicados:
//  1. Agregados imports faltantes (material, riverpod)
//  2. Corregido ColorScheme.fromSeed (faltaba el tipo)
//  3. Corregido MainAxisAlignment.center (faltaba el tipo)
//  4. Agregado WidgetsFlutterBinding.ensureInitialized() antes de dotenv
// ============================================================
