// share the read-only singleton trio; sequential tests mutate cluster state
// (stop/start nodes, predastore, EIP pool) and are ordered so the cluster is
// fully restabilised before later tests probe the trio.
//
// Pre-flight (/dev/kvm writability, peer SSH reachability) runs inside
// requireMultiNodeFixture itself, so the package fixture singleton fails
// fast with a clear message before any Test* body executes.

// Baseline test owns a dedicated SG and self-cleaning instances; it runs
// before needInstanceTrio so the default SG/subnet/route table are in
