# One stack stands up the whole system. Configuration is entirely env-driven
# (see .env.example). Run from this directory: `docker compose up -d`.
#
# backend/frontend are PULLED from the public registry (git.jpaul.io); CI pushes
# them to the LAN endpoint (192.168.0.2:1234). For local building instead of
# pulling, layer the dev override:
#   docker compose -f docker-compose.yml -f docker-compose.dev.yml up -d --build
