//! Replace Financial Advisor configuration example (async).
//!
//! Replaces the FA groups or aliases XML on the server. Reads the
//! replacement XML from stdin.
//!
//! This is a **destructive** operation — it overwrites the FA
//! configuration on the connected account.
//!
//! ```bash
//! cat new_groups.xml | cargo run --example async_replace_fa -- groups
//! ```
