Skip-on-missing-Chromium lets this pass unmeasured. Fail in the forge check (e.g. when FORGE_CHECK is set) instead of logging. |

The guard is right to fail in the forge check, but it will turn this pull red if the check image has no Chromium. Confirm the image has one before relying on it, and name that in the description. |

The numbers are only console.logged. That is fine, but the description needs them from a real run, since the 390px claim is otherwise unverified. |

This restates the constants it imports; it would not fail on a real overflow. Remove or replace with a check of the actual capture.
