1//! [`ApplyHwClusterPin`] impl for [`StaticBackendDispatcher`].
2//!
3//! Forwards to the CSM backend's hardware-cluster-pin orchestration
4//! (HSM group create/delete + member migration driven by an xname
5//! pattern). Ochami's `Ochami` type uses the trait's default body —
6//! calls routed there return [`Error::Message`] with a
7//! "not implemented for this backend" payload.
