"""
gunicorn.conf.py — Gunicorn configuration for VideoPress.

Key choices:
  worker_class = gevent
      Gevent workers are required for Server-Sent Events (SSE).  A standard
      sync worker would block on the SSE generator and starve other requests.
      Gevent patches blocking I/O so each SSE stream is handled as a
      lightweight greenlet, not a full OS thread.

  workers = 1
      FFmpeg compression jobs are stored in an in-process dict (active_jobs).
      Multiple worker *processes* would not share that state.  Keep workers=1
      and let gevent's concurrency handle multiple simultaneous HTTP clients.
      If you need multi-process resilience, replace the in-process job store
      with Redis or a database.

  timeout = 0
      SSE streams are long-lived; the default 30-second worker timeout would
      kill them.  Setting timeout=0 disables the timeout entirely for gevent
      workers (gevent uses its own internal greenlet scheduling).
