Three verdicts from the phone

The PERFECT spark ring is out — the hitstop, the click and the praise word
already carry the moment. The net-cord wobble drops to ~1 px. And the
floodlight stutter is gone entirely: on the iPhone a random dark dip over
the stands reads as the crowd flickering black — a rendering bug, not
ambience.
