It works locally but not on the fly.io deployment. I suspect the favicon.ico is not getting packaged up inside the Docker image. Need to work out a way to get it on the cloud machine. Maybe this?
Fixed in 1ebfa94. I added a code generation tool which writes the favicon's bytes to a Go file, so it can be included in the compiled binary. It's kind of nasty, but it works.
