//! The system clipboard, and the file that stands in for it under test.
//!
//! Three commands touch the clipboard: `pass copy` and `ssh` put a secret on
//! it, `cookie set` reads a header copied from a browser. A test of any of
//! them used to write to the real clipboard of whoever ran the suite - a
//! password over whatever they had copied - and could only run where a
//! clipboard exists at all, which left Linux runners untested.
