Proof

@react-native-community/slider

native-seam only — the real 5.x Slider, StepMarker overlay, limits and defaults run from the bundle over the RNCSlider component view (engine canvas slider). drag values clamp to lower/upper limits and report through the platform event (onRNCSliderValueChange on iOS, onChange with fromUser on android); inverted mirrors like the native scaleX(-1) transform. vertical is a matched no-op (unread by iOS and android upstream).
