  "t2i_prompt": "Overlay on the existing black-and-white rooftop dwelling interior base plan. Add a floor-level camera marker just outside the young adult room door on the living kitchen side, tight to the threshold and door edge. Draw a triangular camera wedge aimed through the slightly open inward-swinging door toward the back-right fabric curtain, with a wide dashed WS field-of-view cone passing through the narrow door gap. Label the camera CAM-S12-Shot4 (WS, low angle, low height). Show the young adult room door slightly open, with the door edge and worn threshold emphasized as a foreground slit frame. Inside the young adult room, add a dense wet dark fluid stippled region across the lower-middle floor area, and a smeared reddish marker footprint trail dragging diagonally from that region toward the fabric curtain at the outer wall. Keep the curtain as the destination point in the background area. No people or figure markers. Use muted gray, muddy dark, and restrained reddish annotation tones over the clean 2D plan; maintain top-down technical architectural drawing style.",
