Static Shoji Screen with Shifting Daylight

the prompt

ACTION: The paper starts dim. A cooler daylight brightens across the panels as if a cloud has passed, then holds. The wood lattice does not move. This is not a door opening. Not a wipe.

FOCUS: Tack-sharp on the paper fiber and one kumiko joint at center. Edges stay in frame.

PHYSICS: Light changes. Wood and paper stay still. No warp. No camera drift.

LIGHT: Diffuse daylight through paper only. No electric color. No hard sun disk drawn on the paper.

STYLE: Photoreal cinematic, period Japan, worn wood and washi tooth, soft grain. No anime. No text. No watermark. No logos.
