In detail

⚠️ Prerendering that branches on user agent is a high-risk configuration: serving full HTML to conventional search engines and a shell to AI crawlers zeroes out every piece of content work, and nothing but a crawl-log check will reveal it. The test is comparing response sizes for the same URL across user agents.
