Use the small bedroom doorway as the shot frame: place a triangular camera wedge just outside the small bedroom threshold in the living kitchen, very low near the floor, pointing through the slightly open inward-swinging door toward the curtain zone at the far side of the bedroom. Add a wide dashed FOV cone labeled \"CAM-S12-Shot4 (WS, low angle, floor-level lens height, through-door mid-pan)\". Emphasize the door edge and threshold as a narrow foreground slit. On the visible small bedroom floor, add a dense glossy dark fluid stippled region in the lower middle to central midground. Add smeared reddish footprint markers leading diagonally from that region toward the curtain at the back right. Mark the fabric curtain as the destination point of the trail. Do not add any human figure marker. Keep all additions as precise 2D technical overlay symbols on the base plan, with clean annotations and no 3D perspective.",
