# Run the Playwright end-to-end suite against the locally running dev server.
#
# Pre-requisite: dev server is up (`./run_dev.sh` in another terminal).
#
# Usage:
#   ./run_e2e.sh                 # default: headless, fast
#   ./run_e2e.sh --visible       # show the browser window
#   ./run_e2e.sh --visible --slow # show the browser AND slow it down to 500 ms/action
#   ./run_e2e.sh --debug         # opens Playwright Inspector for step-by-step debugging
#   ./run_e2e.sh -k <pattern>    # forwarded to pytest, e.g. -k satellite
#
# Any flag we don't recognize is passed straight through to pytest.
