Check a domain’s BIMI record

Reads the BIMI record and the DMARC policy behind it, because a logo only ever appears once DMARC is enforcing. The logo file itself is not fetched — browsers cannot read it, and calling it valid would be a guess.

The lookup runs in your browser. The domain you type goes to Cloudflare’s DNS resolver and nowhere else — there is no server of ours in between.
