//! #1604: a document opened by a path relative to the working directory finds its relatively
//! linked images, as when opened by its absolute path. Its own test binary: it changes the
//! process's working directory.
// Integration tests: unwrapping and panicking on failure is fine here, unlike in shipped code (AGENTS.md › Robustness).
