# launcher.py
"""Dedicated entrypoint for the standalone Windows portable launcher.
Handles:
- Immediate GUI splash screen creation using tkinter.
- Suppressing console stream crashes in windowed GUI mode via NullWriter.
- Spawning system tray icon via pystray and Pillow (lazy-loaded).
- Auto-opening default browser pointing to the running backend.
- Launching the FastAPI server (importing and running app.py).
