Layer

class Layer(
    val id: UUID = UUID.randomUUID(), 
    parentComposition: CompositionContext, 
    content: @Composable



 () -> Unit
)

A self-contained UI layer with its own independent LayoutNode tree and Composition.

Layers are used to implement overlapping UI surfaces such as modals, dropdowns, and tooltips. Each layer has its own root node that is measured and rendered separately from the base screen content.

Layers are managed by LayerStackManager. Do not create or dispose Layer instances directly; use LayerStackManager.push or LayerStackManager.modal instead.
