interactionScale property
The scale factor applied when the user presses the widget.
1.0= no scaling1.15= a fixed 15% grow on press1.3= a fixed 30% grow on press
When null, each widget uses its own default — GlassButton sizes the
press as iOS 26 does, growing its longest side by ~17 pt (1.3× for a
56 pt circle, 1.13× for a 132 pt pill); chips, sheets and menus use
small fixed factors.
