The DisappearingScaffold hid its top/bottom bars purely from overscroll gestures, so a feed with too few items to scroll would end up with two empty bands where the chrome used to be. Pure overscroll (consumed.y == 0) from the fully-visible state is now ignored; once the bars have started moving we know the list is scrollable and edge overscroll keeps feeding bar motion as before.
