SCENE: Overhead locked close-up, 16:9, on a ceramic water bowl beside a dark inkstone. An adult hand, thirties, holds a wet brush above the water. Face out of frame. No readable characters anywhere. ACTION: One drop of black ink leaves the brush and hits the still water. The bloom spreads in rings, then filaments. The hand holds. No second drop. No writing stroke. FOCUS: Tack-sharp on the impact and the ink edge. Bowl rim stays sharp. Background wood is soft. PHYSICS: Ink is heavier than water at first, then diffuses. No instant full-black. No CGI sphere. LIGHT: Window light from the left, a small specular on the water meniscus. STYLE: Photoreal cinematic, period Japan, ceramic glaze and wood grain, soft grain. No anime. No text. No watermark. No logos.
