//! Basic single-listener server example.
//!
//! Binds one [`Server`] on an ephemeral loopback port, serves it for a short
//! fixed window, and shuts down. A real deployment would normally bind a
//! fixed port and run until an external shutdown signal.
//!
//! Run with:
//!
//! ```text
//! cargo run -p irtt-server --example basic_server
//! ```
