# CI harness runtime (M4): a reproducible Python env with pytest + Playwright and the
# Nix-provided browsers, exposed as `cc-ci-run` on the host so the Drone exec pipeline (and
# manual dev) can run the harness with `cc-ci-run runner/run_recipe_ci.py`. Playwright on NixOS
# needs the browsers from nixpkgs (not a downloaded copy) via PLAYWRIGHT_BROWSERS_PATH.
