anchorStretchSettings property
Fine-tuning for the anchor stretch effect.
Controls intensity, squash, translation damping, and bounciness.
When null, GlassButton uses a native tremor default — very gentle
(intensity 0.1, squash 0.1, no bounce), matching the ≤5% elongation
measured on iOS 26 glass. Other widgets fall back to their own defaults.
