//! `BanksClient` backend — **interface stub** (not yet implemented).
//!
//! Wraps a `BanksClient` against a test validator. Like [`super::ProgramTestBackend`]
//! it is a stub: [`ExecutionBackend::run`] returns
//! [`crate::Error::BackendUnimplemented`]. For real compute-unit metering today,
//! use the `cu-profiler-mollusk` integration crate; this stub documents the
//! intended shape and is on the [roadmap](https://github.com/MerlijnW70/cu-profiler/blob/main/ROADMAP.md).
