"""
WSGI entry point for ClassPulse.
This file enables running the application with production WSGI servers like Gunicorn.

The factory initializes the schema (create_all) and reads all configuration
from the environment / .env — see .env.example.

For Flask-SocketIO the WSGI callable is the Flask app itself — SocketIO
installs middleware that handles /socket.io/. With the default sync/gthread
workers Socket.IO uses HTTP long-polling; run a single worker process unless
SOCKETIO_MESSAGE_QUEUE points at a shared queue (e.g. Redis), because
broadcasts do not cross process boundaries without one.
