A small ambient icon for empty states built on real mezzotint printmaking: the plate is rocked to a dense burr that would print solid black, then worked SUBTRACTIVELY as light is scraped and burnished in. The registry's only subtractive glyph mechanic, where every other component builds density up from empty.
