Both frames render identically — that's the goal. The win is in the bytes and requests below, not the look. They're served live by the mod_pagespeed module on demo-httpd-1.1.modpagespeed.com; the optimized frame applies only this filter. Right after a cache purge it may briefly match the original while the worker rewrites it — reload to see the result.
