+	# 📌 IT ADVANCES THE ONE SHARED CLOCK, which is why `authored/flow.json`'s
+	# `clock: "shared"` stands. Both agents briefly had the opposite: a first pass
+	# reported the artwork animating across the press, which would have meant two
+	# clocks and an overlay-only jump. That rested on a 5-frame window which sat
+	# entirely inside the 11-12 frame lag between a scripted press and its effect,
+	# so it compared frames where the input had not been acted on yet. A wider
+	# pre-registered test refuted it: three elements mid-fade vanish in a single
+	# frame. I had implemented the overlay-only version; it is reverted here.

+	# ⚠️ The target is BOUNDED, not pinned. The capture puts it inside [100, 238]
