Opening a folder on this engine differs from the cabinet in one way that
matters for the animation: the cabinet swaps the content 69 frames into the
decide leg, this engine swaps when its loader is done, which can be a couple
of seconds for a big folder. The leg clock parked one frame short of the swap
(f113), i.e. with the decided board already furled away and the neighbours
flown out, so the screen sat empty for the whole load -- and before that the
engine re-grows the decided box's yellow frame, which made the board close
and reopen right after the press.
- The open leg now parks one frame short of the furl (f99): the decided board
stays up, contents faded per the clip, as the loading state. On the swap the
clock resumes from the furl, so furl (f100..113) and the new board's unfurl
(f114..) play back to back; a swap that lands before the park point just lets
the clock run.
- The neighbours' fly-out (f86..99) plays before the swap as on the cabinet;
it used to wait for the swap and then jump straight to the off-screen hold.
- The decided board is remembered at OPEN_BEGIN and drawn fully open for the
whole leg, past the engine's closed re-grow and past the moment the engine
takes the box off the wheel for the loader (draw_overlays bridges it from the
still-live box handle until it has furled).
- The new content's song / back board is not drawn before the swap frame.
