# polyrouter self-host stack (#22, spec §13): app + postgres + redis (+ an
# optional apprise fan-out service behind the "apprise" profile). Product
# compose — dev infrastructure lives in docker-compose.dev.yml.
#
#   ./install.sh            # generates .env (secrets) and boots the stack
#   docker compose up -d    # or manually, once .env exists
#
# The app publishes on LOOPBACK by default: the first sign-up becomes the
# admin, so claim the instance before exposing it (set POLYROUTER_HOST=0.0.0.0
# and APP_URL in .env, ideally behind a reverse proxy with TLS).
