020 * One widget in a {@link BarSlot}: either a {@link BarBadge} (a labelled count, e.g. "N change pending") or a
021 * {@link BarText} (a static contextual label).

024 * Sealed for the MVP: the permitted implementers are frozen so the views emitter's {@code instanceof} dispatch and
025 * {@link BarSlot#validate()} are total.  No fourth implementer compiles.
