131 of the 135 Back skeletons have no Die clip, so SpineActor.die() changed nothing and the
attack / skill / idle loop went on under the redeploy ring. UnitView._wantsBack() now wants the
Back model only while the unit stands (or when its Back skeleton has a Die clip of its own);
die() / revive() mark the view and its update swaps the model in place after the frame's events
(a death and a redeploy in one frame load nothing). The Front model replays the fall (held end
for a unit already down), gets the knocked-down grey, and the redeploy brings the Back model back
with the deploy clip carried over. A skeleton without a Die clip holds its idle's first frame.
