//! Sleep capability trait.
//!
//! Abstracts async sleep so that native code can use `tokio::time::sleep`
//! while wasm delegates to `setTimeout` via `JsFuture`.

    ///
    /// Stateless impls return a unit struct; stateful impls (mock clocks,
    /// virtual time sources, etc.) should return a sensible default. Callers
    /// that don't have an instance handy can use the static-style
    /// `C::new().sleep(duration)` pattern, mirroring `HttpClientCapability`'s
    /// `new_client()` + `request(&self)` shape.
