// Run with Node's test runner and Playwright on the module path; see README.md.
// A group member whose proxy wasn't listening (#381: 127.0.0.1:1082 down,
// "proxyconnect tcp: … connection refused") hands the request to the next:
// the Routing page's story says the request never reached it and that it
// doesn't rest, in the page's language, rather than "an error another
// account wouldn't fix".
