"""
Entry point for cPanel's "Setup Python App" (Phusion Passenger).

Passenger expects a WSGI callable named `application` in this file.
FastAPI is ASGI-based, so we wrap it with a2wsgi's ASGIMiddleware to
bridge the two — everything else in the app (routing, background
training threads, prediction endpoint, file uploads) works unmodified.

cPanel setup:
  - Application startup file : passenger_wsgi.py
  - Application Entry point  : application
  - Make sure `a2wsgi` is in requirements.txt and installed via
    cPanel's "Run Pip Install" (or `pip install -r requirements.txt`
    inside the app's virtualenv over SSH).

Unlike Render, Passenger does NOT use a $PORT env var — it manages the
process and routes HTTP through Apache/LiteSpeed itself, so run.py is
not used in this deployment path.
