Groups compose multiple slivers along one axis inside a single viewport; constrained and expanded wrappers control cross-axis shares.

Group	Composition
`SliverMainAxisGroup`	Stack slivers along the main axis
`SliverCrossAxisGroup`	Arrange slivers across the axis
`SliverCrossAxisExpanded`	Proportional cross-axis share (flex `>= 1`)
`SliverConstrainedCrossAxis`	Max cross extent cap
