report.rs

//! Terminal rendering.
//!
//! A run produces a lot of state; the report exists so the operator can decide
//! what to do next without opening `run.json`. It leads with the disagreement,
//! because that is the part that carries information: three judges agreeing
//! tells you nothing the winner's diff does not.
//!
//! Colour is a six-line local implementation rather than a crate. The
//! alternatives all decide *for* you whether the stream supports colour, which
//! makes the output untestable — `assert!(text.contains("winner  A"))` fails on
//! an escape sequence the test never asked for.
