  // The package build compiles `src` only, so the test tree was never
  // type-checked from inside the package — and the device-scope guard is
  // *written* as `@ts-expect-error` probes in the tests, which are inert unless
  // something type-checks them. Run this alongside the build typecheck so the
  // guard holds in the package itself rather than depending on a root-level
  // glob happening to reach it.
