  "t2i_prompt": "Overlay on the existing rooftop_room_interior base floor plan only; keep all base furniture and architecture unchanged. Add a triangular camera wedge labeled CAM-S12-Shot4 (WS, low angle, low, floor-level observer, mid-pan hold) on the living room side of the 수리영 방 doorway, just outside the threshold. Point the wedge through the slightly open bedroom door toward the back-right curtain/window area. Draw a wide dashed FOV cone passing through the narrow doorway gap, with the door edge and threshold acting as a foreground slit frame. Inside 수리영 방, add a dense glossy dark fluid stippled region across the lower-middle floor just beyond the threshold. Add smeared reddish marker footprint shapes dragging diagonally from that region toward the back-right fabric curtain. Mark the curtain at the back-right window as parted fabric with subtle texture. No character markers in this shot. Use cold blue-gray floor shading with weak amber spill from the living room practicals.",
