  "t2i_prompt": "Overlay on the existing black-and-white architectural interior floor plan. Use the rooftop room interior plan as the base. Add a floor-level camera marker on the living-kitchen side of the small bedroom doorway, just before the threshold. Draw a triangular wedge symbol pointing through the slightly open bedroom door into the small bedroom, with a dashed wide FOV cone clipped by the door gap and extending diagonally toward the curtain/window side. Label it exactly: CAM-S12-Shot4 (WS, low angle, low, floor-level through-door hold). Show the small bedroom door slightly open inward, with the door edge and threshold acting as a foreground slit frame. In the small bedroom floor trace zone, add a dense irregular dark fluid stippled region just beyond the threshold and lower middle of the room. From that region, add smeared reddish footprint-like traces dragging diagonally toward the fabric curtain at the back-right/window side. Show the fabric curtain as the destination point, using simple paired fabric lines; do not add any human figure marker. Keep all overlays technical, top-down, monochrome plan style except the dark stipple and reddish trace annotations; no 3D perspective, no extra characters, no named places, no personal names.",
