Kaagaaz/SpectraGuard ? reverse-engineered prompt

Build me a simple modern website that lets someone paste in a public website URL and instantly see how secure and privacy friendly it looks.

I want it to check things like whether the site uses HTTPS, important security headers, cookie settings, common tracking scripts, and basic technology detection, then turn that into an easy to understand security score with a clear risk level. Show the results in a clean report view with friendly explanations so non experts can understand what each finding means.

Make it feel polished and fast, with a nice homepage, a scan result page, and a report page. Use plain HTML, CSS, and JavaScript for the frontend, and a small API that can run on Cloudflare Workers to do the passive analysis. Please keep it safe and only use publicly available information, no hacking or active testing.

If you need to look up current docs or best practices while building it, feel free to do that.
