Design principles

Useful before flashy

Tool first.The useful function appears before long explanations.
Explain failures.Where possible, tools identify likely causes and next checks.
Privacy-conscious.Client-side processing is preferred for sensitive artifacts.
Engineer-grade.Outputs expose the details professionals actually need.
