  "t2i_prompt": "Overlay on the existing base floor plan only; keep all base walls, room divisions, furniture, bed, curtain, and layout unchanged. Add a triangular camera wedge on the floor just outside the small bedroom doorway, on the shared living-area side of the threshold, labeled `CAM-S12-Shot4 (WS, low angle, low lens height, static observer)`. Point the wedge through the narrow opening of the slightly open inward door toward the back-right curtain area. Draw a wide dashed FOV cone passing between the door edge and the jamb, using the door edge and worn threshold as a near-foreground slit frame. Inside the small bedroom, add a dense glossy dark fluid stippled region across the lower-middle floor area just beyond the threshold. Add smeared reddish footprint markers dragging diagonally from that pooled floor mark toward the back-right curtain/window zone. Show the fabric curtain as parted in the middle and dimly lit, with the footprint trail ending at that curtain area. Add subtle blue-gray floor spill with a weak warm edge-light note; do not add any human figure markers.",
