A short message that rises in from just below where it rests, out of a slight blur, and leaves the same small way. Newer toasts stack in front and older ones tuck in behind, a little smaller and dimmer; hover the stack to spread it out. When a toast changes, its words and icon morph in place. A pill variant puts the whole message on one dark line, and a single manager makes each new message take the place of the last. Built on Base UI, animated in CSS.
