# Run E2E tests (Playwright) against the Docker-composed test stack.
# Builds the app, starts the stack, runs tests, then cleans up.
#
# Usage:
#   ./scripts/run-e2e-tests.sh                    # run all E2E tests
#   ./scripts/run-e2e-tests.sh --headed           # run with browser visible
#   ./scripts/run-e2e-tests.sh generation-live     # run specific test file
#
# Prerequisites:
#   - Docker and docker compose
#   - Node.js (for Playwright)
#   - OPENAI_API_KEY env var (for generation-live test)
