Class UserSession

java.lang.Object
com.example.cab302project.UserSession
public class UserSession extends Object
Manages the global authentication state for the application. This class uses a Singleton-like pattern to store the currently logged-in User. It provides centralized access to user preferences (like Dark Mode) and permission levels (like Police status) across all UI controllers.
