Häufige Annahme

A setting named `GODEBUG=http2server=0` only affects debug output, so an explicit HTTP/2-only setup should still work.

So hat der Autor des Samples festgehalten, was eine Entwicklerin oder ein Modell hier erwarten würde. Der Vertrag darunter ist das, was tatsächlich lief.

Contract

An HTTP/2-only client-server pair should negotiate and return `HTTP/2.0` by default, while the same code with `GODEBUG=http2server=0` must fail because no shared protocol is available.
The helper run under `GODEBUG=http2server=0` exits with a non-nil request error instead of returning a 200 HTTP response.
