/// The <c>/v1/ping</c> endpoint that previously lived here was
/// removed during the [Host]-strip refactor — both geo and ns
/// answered the same path (NsController.Ping is the canonical
/// one), and with host filters gone the two routes would have
/// ambiguous-matched on any subdomain. NsController wins because
/// its ping body carries the timestamp the keep-alive loop reads;
/// the geo version returned a bare {Ok:true} that nothing consumed.
