# Fornax distributed torrent workers — each is a gluetun+qBittorrent pod on a different VPN server
# Worker TX#179: US-TX#179, NAT-PMP via gluetun native ProtonVPN port forwarding
# Worker TX#220: US-TX#220, NAT-PMP via gluetun native ProtonVPN port forwarding
# Both workers share the media-data PVC; each has its own config PVC and VPN credentials
# Port file shared via emptyDir: gluetun writes /tmp/gluetun/forwarded_port, helper reads it
