The application's main flow begins with AppModule bootstrapping the AppComponent. The AppComponent then utilizes ConfigService for application-wide settings, FullscreenLoadingService for managing UI loading states, and InstanceService for global application state. These services are provided at the AppModule level, ensuring their singleton availability throughout the application.
The primary Angular module that bootstraps the entire application. It acts as the root module, orchestrating the loading of other modules, declaring the root AppComponent, and making application-wide singleton services available through its providers. This is fundamental for an Angular application's startup.
