# Smoke tests for davinci-platform.
# Validates core endpoints are responding correctly.
#
# Ports are configurable via environment variables so the smoke tests
# can run against either the dev stack (3001/3000) or the isolated test
# stack (3101/3100).
#
# Usage:
#   bash smoke-test.sh                        # Against dev stack
#   API_PORT=4301 WEB_PORT=4001 bash smoke-test.sh  # Against test stack
#   SKIP_WEB=1 bash smoke-test.sh             # API only (no web container)
#   make smoke                                # Against dev stack (via Makefile)
