Happy to see an update!

I may have had a related issue, I remember having trouble with redirects
on tilde.black and gemini.conman.org. In the end the issue was that they
were closing *right after* sending the redirect, I think, and I wasn't
capturing the last few bytes. But I was using Go, not Flutter, so I'm not
sure how much this helps.
