# Note: SocketIO requires sticky sessions for multi-machine deployments.
# With min_machines_running = 1 and auto_stop_machines = false, a single machine
# handles all connections, avoiding the need for Redis-backed session storage.
# If you scale beyond 1 machine, add sticky sessions via fly.io HTTP service options.
