ludic.ui, runtime: the last per-frame allocations in the interface - the top popover found without a list, the popover draw list and the clip stack kept, a select's options in a list the node keeps (and matched to its value without writing the index), a number's text kept on its Value until it changes (value_num_set / Value.num_text), a key's label kept per key code until the layout changes it
