"""Development entry point.

For production use ``wsgi:app`` behind gunicorn with the gthread worker class.
This module intentionally refuses to start the Werkzeug dev server when
``FLASK_CONFIG=production`` so a misconfigured deploy fails loudly instead of
quietly serving traffic from an unsafe development server.
