Struct DensityMeasureScope 

pub struct DensityMeasureScope { /* private fields */ }

The production cranpose_ui_layout::MeasureScope: a grid captured at composition time, carried through measurement.

MeasurePolicy::measure runs with this as its scope, the way Compose’s MeasurePolicy.measure runs with MeasureScope as its receiver. The grid is the LayoutNode’s own Density – read at composition time by the Layout composable from density, not the host default – so a subtree given a different grid through ProvideDensity is measured on that grid.
