//! Live check against TypeSafe's hosted Jev. Ignored by default; runs only
//! when `TYPESAFE_API_KEY` is set:
//!
//! ```text
//! TYPESAFE_API_KEY=... cargo test --features decision --test decision_live -- --ignored --nocapture
//! ```
//!
//! One batched request with a Noul, a Choice and a Score. The key is never
//! printed.
