//! Importer plug-ins (`"kind": "importer"`, docs/plugins.md › Importers) through the engine: the
//! formats they add to `document.formats` and `document.open`, which files they are given, the
//! document their objects become, and what happens when they fail, decline or are cancelled.
//!
//! A test binary of its own: installed plug-ins are process-wide, and the unit tests that check the
//! exact list of formats would see these ones.
// Integration tests: unwrapping and panicking on failure is fine here, unlike in shipped code (AGENTS.md › Robustness).
