//! Minimal ANSI colouring with no external crate.
//!
//! When colour is disabled (`--no-color`, the `NO_COLOR` env var, or a
//! non-terminal stdout) every helper returns the text unchanged, so callers can
//! colour unconditionally and let the [`Palette`] decide.

/// A colour policy: either emits ANSI SGR codes or is the identity.
