/* Perf pass (performance audit, same day): the sweep originally animated

   container. That forces a synchronous layout recalculation on every
   animation frame — measured on this exact page via a benchmark of 2000
   forced style+layout flushes on a real #tier-map child: ~187us per change
   vs ~2.5us for the equivalent background-position change (~73x). Same
   visual result, driving background-position-y (paint-only, same trick
   already used elsewhere in this file for the NEURAL LINK button's
   `dataStream` keyframe) instead of `top` — no layout cost, every frame,
