Empty

The “nothing here” placeholder — what a gallery shows when a search or filter returns no results, a list is empty, or a panel has no content yet. Three stacked pieces: an illustration, a description line, and an optional action slot (the children, typically a button that clears the filter or adds the first item):

Empty(description = Some(span("No wallpapers match your filters")))(
  Button("Clear filters", onClick = () => reset()),
)

image chooses the illustration via EmptyImage: Default (the full line-art drawing), Simple (a smaller minimal one), Hidden (no illustration), or Custom(node) (your own icon or photo). Both built-in drawings are in currentColor, so they take the surrounding text colour under any skin. description overrides the default “No data” text.

The root is a role=status region labelled by the description (so assistive tech announces the empty state), and the structure is mirrored to data-* (data-part on the root and each piece).
