   - Ensure tests cover new code and pass CI.
   - Flag bugs or critical issues for immediate fixes; suggest non-blocking improvements as follow-up issues.

   - Review promptly to avoid blocking progress.
   - Balance quality and speed—minor issues can be addressed later via issues, not PR blocks.
