//! Custom write destinations — spinners on stderr.
//!
//! Keeps stdout free for structured output (JSON, piped data, etc.)
//! while the user still sees spinner feedback on the terminal.
//!
//! For any `io::Write + Send` target, use `with_writer`. To force
//! ANSI codes on a non-TTY writer, use `with_writer_tty`.
//!
//! Run with: cargo run --example custom_writer
