Polish is often described qualitatively. This research introduces measurable signals that map better to implementation quality.
Core signals
Signal quality includes interaction latency, semantic token coverage, and readability under responsive stress.
The strongest systems maintain these signals in both light and dark themes without one-off exceptions.
Adoption notes
Teams can adopt signals incrementally by adding lint and CI checks for token usage and responsive regressions.
A lightweight scorecard keeps quality discussions specific and actionable.
