1. Prepare 2 builds with different CLS
2. Compare them

Expected behavior
See CLS diff same way as any other metrics.

SVG will very likely take a little longer to render than a base64-encoded raster image. And the Gaussian Blur applied to the simple SVG shapes created by Primitive is probably quite CPU intensive.

If we edit the name, we should change it in all places. That is super useful when you compare pages and wanna do screenshots.
