 * here. If there is a predicate and it and returns {@code true}, then

 * ad creative via early XHR CORS request; verify that it is validated AMP;
 * and then render directly in the host page by splicing into the host DOM).
 * Otherwise, it will attempt to render the ad via the existing "3p iframe"
 * pathway (delay load into a cross-domain iframe).
