k-v.io has an A record, a pre-requisite for a website

I've chosen to add the website to GKE, not Hetzner, because I get fewer
strident abuse messages from GKE.

I'm dismayed that when I make a small change to the DNS, I need to go
through the laborious release process for it to take effect. Sigh. Maybe
that's something I'll fix another day.
