"""WSGI entry point for the Team Tryouts application.

This module provides the production WSGI server using Waitress (Windows).
Use this file to start the application in production instead of Flask's
built-in development server.

Usage:
    python wsgi.py
    
Configuration via environment variables:
    PORT: Port to listen on (default: 5000)
    WAITRESS_THREADS: Number of worker threads (default: CPU*2+1)
