Custom gestures do not conflict with system gestures

A PanGestureHandler wired to the root view or main screen swallows the iOS edge-swipe-back gesture — users can no longer navigate back and file crash-level bug reports. Globally-scoped swipe handlers also fight with ScrollView momentum, producing frozen scrolls and ghost taps. Apple's HIG explicitly reserves edge gestures for the system, and conflicts here are a common rejection reason during App Store review.

Scope every custom gesture to the smallest possible subtree and never attach a pan handler at the screen or NavigationContainer level. Use react-native-gesture-handler's simultaneousHandlers and waitFor to coordinate with scroll gestures:

<PanGestureHandler onGestureEvent={onSwipe} activeOffsetX={[-20, 20]}>
  <Animated.View style={animatedStyle}>{/* card only */}</Animated.View>
</PanGestureHandler>

Set activeOffsetX so horizontal swipes on the edge still reach the native navigator.
