- Add "Highlight Min/Max" option to ReadoutPanel showing peak rings. - Reset to review mode and blank wafer map when switching away from map tab. - Disable hover highlights and sensor dialog triggers during live stream. - Lower trendPane height and add top margin headroom for tick labels. - Add test coverage for blanking states, toggle overrides, and interactions.
