  "t2i_prompt": "Overlay on the existing black-and-white architectural floor plan of the compact rooftop dwelling interior. Use top-down technical drawing language, white background, clean linework, no 3D perspective, no human figures. In the small bedroom doorway, place a triangular camera wedge just outside the threshold on the living-kitchen side, pointing through the slightly open bedroom door into the small bedroom. Add a dashed wide FOV cone passing through the door slit and spreading across the small bedroom floor toward the curtain area. Label the camera exactly: CAM-S12-Shot4 (WS, low angle, low lens height, doorway slit frame). Show the bedroom door slightly open inward, with the door edge and threshold emphasized as foreground framing geometry. On the small bedroom floor, add a dense glossy dark fluid stippled region in the lower middle to midground floor trail zone. From that region, add smeared reddish marker footprints dragging diagonally toward the fabric curtain at the back-right window wall. Keep the curtain area as the ominous destination point, with the fabric curtain clearly labeled and still. Use safe graphic notation only: stippled dark region, reddish footprint markers, dashed trail direction arrows if needed. Do not add any person marker, still figure outline, realistic gore detail, or named labels. All rendered graphic labels must be ENGLISH ONLY.",
