//! its own machine — which is why it works where OS access cannot: over SSH, on Wayland without
//! `wayland-data-control`, in WSL, and in a build without the `clipboard` feature. Terminals
//! that don't understand it ignore it. Only the real sources in [`super::source`] emit it, so a
//! test's clipboard never writes escapes to test stdout.
