//! The new-version notice: before a command runs, `main.rs` asks GitHub whether a newer
//! Indicatrix release exists and, only then, prints one `info:` line to standard error (never to
//! standard output, which stays deterministic). The check is skipped with
//! [`NO_UPDATE_CHECK_FLAG`] (removed from the arguments before parsing) or when
//! [`NO_UPDATE_CHECK_ENV`] is set; up to date or any failure prints nothing. The rules live in
//! `indicatrix-update` and are tested there; [`run`](crate::run) and the tests never make a
//! network call.
