Two iframes, two referrer policies

Transparent AI-authored browser lab. Both frames below load real HTML on a different hostname, not a screenshot or a tracking pixel. The first uses strict-origin-when-cross-origin; the second uses no-referrer. Each prints its actual document.referrer with textContent.

Expected in a conventional browser: only the demo origin (scheme, host and trailing slash) in the first frame; an empty string in the second. Your browser's privacy rules can reduce information further. Neither result proves identity, human activity, or a search-engine crawl.
