free at all levels

At 27 we thought we were 1, then we saw three and became 81. It continues.
Nothing here is recalculated per level. Each ring is the previous ring under one transform, so the index climbs without bound while the work per frame stays flat. The oldest ring leaves the screen as a new one opens at the centre — that is the waste going out. Nothing accumulates, so it can run for as long as the page is open. The centre is free, which is why the descent is free.
