    Main function to launch the Flight Monitor application.

    # Initialize the Tkinter root window FIRST
    root = tk.Tk()

    # MODIFIED: Setup basic logging AFTER Tkinter root is created
    # WHY: The Tkinter-based log processor needs a root instance to schedule itself.
    #      The TkinterTextHandler itself will be added later by MainWindow.
    # HOW: Called setup_basic_logging here, passing the necessary arguments.

    # Create the application controller
    app_controller = AppController()

    # MODIFIED: Set the main window instance in the controller *before* creating MainWindow
    # WHY: MainWindow's initialization (specifically MapCanvasManager) might call back
    #      to the controller requesting MainWindow methods (like show_error_message).
    #      If the controller doesn't have a reference to MainWindow yet, these calls fail.
    #      By setting it here, the controller has a reference to the *soon-to-be-created*
    #      MainWindow (self-referencing via `app_controller.set_main_window`),
    #      which allows it to correctly pass itself (with its window reference) to sub-components like MapCanvasManager.
    # HOW: Moved this line before MainWindow creation. It's a forward reference,
    #      but Tkinter's `root` and `app_controller` are already defined.
    #      MainWindow will then internally set its own reference during its init.
    #      NOTE: This is a common pattern for mutually dependent objects.
    main_app_window_placeholder = MainWindow(root, app_controller) # Create the main application window instance
    app_controller.set_main_window(main_app_window_placeholder) # Pass the instance to the controller
    # main_app_window = main_app_window_placeholder # Keep the name consistent

    # Start the Tkinter event loop
    module_logger_main.info("Starting Tkinter main loop.")
    root.mainloop()
    module_logger_main.info("Tkinter main loop finished.")

    # Cleanup is handled by MainWindow's _on_closing method, which in turn
    # calls controller.on_application_exit and logger.shutdown_logging_system.
