Add a low floor-level camera marker just outside Suri-young's bedroom door on the living-room side: triangular wedge pointing through the slightly open door into the room, with a wide dashed FOV cone partially occluded by the door edge. Label it: CAM-S12-Shot4 (WS, low angle, low, static through-door frame). Show the bedroom door slightly open inward, using the door edge and threshold as a foreground slit frame. Inside Suri-young's room, place a glossy dark fluid stippled region across the lower-middle/central floor area just beyond the threshold. Add a smeared reddish marker footprint trail dragging diagonally from the central floor toward the back-right curtain/window area. Add the fixed fabric curtain at the back/window zone, subtly textured in cold blue-gray and weak amber practical spill. No living figure markers and no still figure outlines in this shot.",
