"""
Demonstration script for the modularized Cluster4NPU UI application.

This script demonstrates how to use the newly modularized components and
shows the benefits of the refactored architecture.

Run this script to:
1. Test the modular node system
2. Demonstrate configuration management
3. Show theme application
4. Launch the modular UI

Usage:
    python demo_modular_app.py
