// Golden-test parity: run every case in
// api/services/workflow/node_specs/display_options_fixtures.json through
// the TypeScript evaluator and assert the result matches `expected`.
//
// Run via `npm run test:display-options` from ui/, or `node
// ui/scripts/test-display-options.mts` directly (Node 24+ strips TS types
// natively).
//
// Mirrors `api/tests/test_display_options_evaluator.py`.
