# Minimal self-hosted deployment (internal use: no TLS / reverse proxy).
#
# Flows are the bind-mounted ./backend/flows directory (source of truth);
# the embedded API watcher reconciles them into the DB + LFX automatically.
# Registry images (:latest) auto-update nightly via watchtower; locally
# built images (app, lfx, frontend) update via `docker compose build --pull`.
#
# Usage: docker compose -f compose.prod.yml up -d --build
