 /**
  * SlideToConfirm — pure RN, no RNGH, no Reanimated.
  *
- * Key fix: Animated.event pipes gesture data directly to native thread
- * (no JS bridge delay) — this is what makes the handle actually track the finger.
- * useNativeDriver: true on all animations for 60fps smoothness.
+ * Key findings (Conan investigation):
+ * - Animated.event + useNativeDriver:true is BROKEN with PanResponder — gestureState
+ *   (dx/dy) is JS-computed so native driver skips setValue() entirely. Never use.
+ * - useNativeDriver: false is fine on New Arch (Fabric+JSI) — no bridge penalty.
+ * - onStartShouldSetPanResponderCapture claims gesture in capture phase BEFORE
+ *   the Modal container can contest it on iOS — fixes the delayed-grant lag.
