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

Usage (from the project root):
    python run.py

Production uses Waitress, from the project root as well:
    python wsgi.py

These two are the only entry points. app/app.py exposes the factory and
nothing else.

Environment variables:
    FLASK_DEBUG: 'true' turns on the reloader and the interactive debugger.
        Off by default — the Werkzeug debugger executes code submitted
        through the browser, so a process left running with it on is a
        remote shell. Opt in per session, never in a deployed .env.
    DEV_HOST: interface to bind (default 127.0.0.1, loopback only).
    DEV_PORT: port to listen on (default 5000).
