# Checks tools/serve.py, the preview server that runs the built binary and
# hands its output back over HTTP. The cases live beside this file, in
# serve-split-check.py for how the CGI headers are told from the body and in
# serve-handler-check.py for a request served on a free loopback port with a
# stub in place of cgit. Nothing here touches a repository, so the fixtures
# stay unbuilt.
