      // a quality signal. We demoted these to `warn` so CI stays green while we
      // work through the backlog. Track and clean up items via:
      //   - run `npm run lint` locally to see the current warning list
      //   - follow-up issue: clean up tseslint recommendedTypeChecked backlog
      // Do NOT add new code that triggers these rules without fixing them in
      // the same PR.
