Function layers 

pub fn layers<VT: ViewTuple + 'static>(children: VT) -> impl IntoView

Create a stack of overlapping layers.

Each child view is positioned absolutely to fill the container, making them overlap. This is useful for testing z-index behavior.

Example

let view = layers((
    Empty::new().z_index(1),  // Back layer
    Empty::new().z_index(10), // Front layer
));
