    // **The runtime is built here rather than by `#[tokio::main]`, because the *end* of the process is the part that
    // needs a bound.** Dropping a runtime waits for its blocking tasks, and one of them can be a program being cooked
    // — a second of work after the client has already been told the server is shutting down. `shutdown_timeout` waits
    // for at most that long and then lets the process end. Measured before this: `shutdown` with the client holding
    // stdin open left the process alive, and the goodbye line showed the hang was not in the server's own code.
