RUN chmod +x startup.sh

# NOTE: We intentionally do NOT run test_osm_import.py here. It imports Django
# models before settings are configured (raising ImproperlyConfigured) and needs
# a migrated DB + network — none of which exist at image-build time. As a `RUN`
# step it failed every build, which silently broke Coolify deploys (the old
# container kept serving). Tests run in CI (.github/workflows/ci.yml) instead.

# Expose port
EXPOSE 8000
