//! `01_quickstart` — single Anthropic Messages call.
//!
//! Build: `cargo build --example 01_quickstart -p entelix`
//! Run:   `ANTHROPIC_API_KEY=sk-... cargo run --example 01_quickstart -p entelix`
//!
//! This binary makes a real API call when run with credentials, so CI
//! validates only that it compiles. See `HANDOFF.md §9` for the live-test
//! cost trigger.

#![allow(clippy::print_stdout)] // example output goes to the terminal
