//! [`StatisticsPort`] — operational counter surface.
//!
//! Every [`DeliberateUseCase`](super) invocation that completes
//! records its duration and specialty through this port; every
//! [`OrchestrateUseCase`](super) invocation records the orchestration
//! duration. Adapters decide where the numbers live — in-memory for
//! a single replica, external store for multi-replica setups — and
//! whatever Prometheus / gRPC exposer the composition root wires
//! reads [`Statistics`] through `snapshot`.
