# Docker container entrypoint for ShopDB Flask.
# Waits for the database to answer, then starts whatever it was given.
#
# This deliberately does NOT run migrations, plugin bootstrap or seeds. That
# sequence lives in the `migrate` service in docker-compose.yml (and its
# equivalents in the pull/airgap compose files) so there is exactly one place
# it happens. Running it here as well would mean every api restart re-attempted
# schema work, and a failing migration under `restart: unless-stopped` would
# crash-loop and bury the original error under retry noise.
#
# `up -d api` is still safe on its own: compose honours the
# service_completed_successfully dependency even when a single service is
# named, so the migrate service runs to completion first.
