Full *arr stack in one compose file

Why This Unified Stack Exists

The Homelab Problem: Six *arr tabs that do not share a network or a downloads folder.

Verified Containers in This Recipe

Unified Multi-Container docker-compose.yml

All services below share a dedicated bridge network (lanternrack_net) and consistent PUID/PGID permissions so containers can communicate by hostname without exposing internal database ports.
