The live audit reported "crawlers were served different bytes" for
/privacy-policy on qn.isnull.dev. That reads as the origin choosing what to
serve by user agent, which would be serious. It is not what is happening:
Cloudflare's email obfuscation rewrites the privacy address on that front door
with a token that changes on every response, so any two fetches differ.
The audit now asks the same agent twice before blaming the agents, and says
which of the two it found. A misleading finding is how a checker gets ignored.
Refs #228.
