"""Run the JS tests for `webui/static/discover-section-controller.js`
under the regular pytest sweep.
The actual contract tests live in
`tests/static/test_discover_section_controller.mjs` and run via
Node.js's stable built-in test runner (`node --test`). This shim
shells out to that runner and asserts a clean exit so the JS tests
fail the suite if the controller contract drifts.
Skipped when:
- `node` isn't on PATH (e.g. Python-only dev container).
- Node version < 22 (the built-in `--test` runner went stable in 18
but the assert-flavor we use is 22+).
Run directly:
node --test tests/static/test_discover_section_controller.mjs
