Reference

Constant	Value	Description
InitialColumnCount	3	Default starting columns

ThresholdFraction	0.45f	Scale change needed to trigger snap
DeadZone	0.01f	Micro-movement filter to prevent jitter
PinchOutThresholdMultiplier	0.85f	Makes pinch-out 15% easier than pinch-in
TransitionSpec	None	Google Photos-style instant reflow
