# Cucumber harness for the PAYG shadow-mode scenarios. Brings up the
# saas-profile docker-compose, waits for backend health, pipes the seed SQL
# into the test postgres, then invokes Behave against features/payg/.
#
# Companion to testing/test.sh (which covers the proprietary-flavor stack
# and skips features/payg via behave.ini's exclude_re). Kept as a separate
# entrypoint so the saas variant can be reviewed + iterated on without
# touching the main cucumber harness.
