A popover/hover-card whose opened/closed state is a pure function of the timeline. The Popover renderer is a pure function of a PopoverStyle (opacity, scale, translate); usePopoverTransition eases both the open and the close. The static `side` prop sets the enter translate axis; renders title + description and/or arbitrary children in a popover card.
