// The JS half of the PHP<->JS export cross-check. Both the browser generators
// (here) and the PHP generators (tests/Unit/Export/CrossCheckTest.php) are
// pinned to the same golden fixtures under tests/Fixtures/export, so the CLI and
// the dashboard download produce byte-identical files for the same schema while
// both implementations coexist (until the Phase 3 route swap deletes these JS
// generators). Equal-to-the-same-file means equal to each other.
