  • Use effects sparingly while keeping state, interruption, and reduced-motion behavior clear.
  • Collect, validate, and report form state accessibly.
  • Integrate remote data with explicit loading, failure, and cancellation behavior.
  • Contain plugins, reproduce defects, and add regression checks before changing legacy behavior.
  • Modernize one tested boundary at a time while keeping the application deployable.
