Returns: resource counts (scripts, stylesheets, images, iframes, audio/video, resource hints); how many external scripts are parser-blocking vs async/defer/module; how many inline scripts run synchronously; how many stylesheets are render-blocking (print-only and disabled sheets excluded); inline JS/CSS byte sizes; an estimated network request count; and an estimated transfer-weight budget. The HTML's own byte size is measured exactly; external sub-resource sizes are ESTIMATED from typical median file sizes (no network is used). Set output='json' for a structured object, or list_resources=true to also list every external resource URL. Use it to spot render-blocking resources, over-large pages, and too many requests.",
