  * SlideToConfirm — pure RN, no RNGH, no Reanimated.
  * PanResponder on handle + Animated(useNativeDriver:false).
  *
- * Fix: live refs break stale closures — disabledRef + onConfirmRef
- * updated on every render so PanResponder always reads current values.
+ * Fix history:
+ * - v1: stale closure fix — disabledRef + onConfirmRef
+ * - v2: trackWidth=0 snap bug — trackWidthRef+State, startPos/currentPos refs,
+ *       eliminated _value/_offset private API, layout guard on gesture start
