# Install system dependencies.
# - postgresql-client: alembic / psql tooling
# - dos2unix: entrypoint line-endings
# - libxml2-dev, libxmlsec1-dev, libxmlsec1-openssl, pkg-config:
#     required by python3-saml (XML signature validation)
# - libsasl2-dev, libldap2-dev, libssl-dev:
#     required by python-ldap if used (ldap3 is pure-python so optional,
#     kept here for future flexibility)
