In the living room, just outside the small bedroom doorway, place a triangular camera wedge near floor-level position, pointing through the slightly open bedroom door into the small bedroom. Add a wide dashed FOV cone passing through the door slit and aiming diagonally toward the rear-right curtain. Label it: CAM-S12-Shot4 (WS, low angle, low, through-door frame). Show the small bedroom door slightly open inward, with the threshold and door edge emphasized as a foreground framing device. Inside the small bedroom, add a dense glossy dark fluid stippled region across the lower-middle floor area. From that region, draw repeated reddish footprint markers with smeared edges leading diagonally toward the rear-right fabric curtain. Keep the curtain visible as the ominous destination point, subtly textured and parted at the center. Add a faint blue-gray and weak amber lighting wash annotation from the adjacent living area. No human figures, no extra furniture changes, no 3D perspective.",
