+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).
