Enum Layer 

pub enum Layer {
    Overlay,
    Notice,
}

Which floating surface sits over which, named by what floats.

Two roles and no ladder: an overlay is a scrim and the panel in it (a modal, a picker that covers the page); a notice is a transient message, which stays readable over an open overlay. Everything else stacks in document order. Unitless z-index values, the same at every density.

Variants

Overlay

A scrim over the page and the panel it holds.

Notice

A transient message, above an open overlay.
