The trigger event is identical in every frame — a single millisecond, embalmed — while everything around it ages: the sun walks its setting diagonal and sinks, the chamber keeps running (history accumulates), the grain grows as the light dies, and the water remembers: the wave rows slowly bend around the submerged evidence. The sea never reacts in the instant; influence arrives only through time. The hand tracks the descent — ghost-rings where the sun was, altitude readings, and when the sun is gone, a guess.
