    "prompt": "Photorealistic cinematic interior background. Convert the architectural floor plan reference (top-down diagram) into a 35mm film-style photoreal view of the actual room from inside, eye-level wide angle, single static frame, no people. Match the reference floor plan layout EXACTLY: this is ONE single rooftop room (옥탑방) on top of a building — NOT a multi-room apartment, NOT a living-bedroom-kitchen suite. The whole interior is a single 5m-wide room with the layout described below. Layout from this view (camera near the front-right corner looking toward the back-left): Left wall: ONE small old CRT television on a low wooden stand (single TV, do not draw a second TV anywhere) and a worn fabric sofa in front of it. Back wall: kitchen counter with a stainless sink in the middle, a small window with a thin curtain to the right of the sink, and a narrow plain interior doorway (closed) at the far back-right corner — this doorway leads to a tiny adjoining bedroom space (do NOT show its inside). Right wall: a simple wooden dining table with two or three chairs. Front-right (near the camera): the outer entry door is offscreen-right, ignore it for this view. Material/lighting: dirty plaster walls in muted yellow-gray, worn wooden floorboards, low ceiling with a single bare bulb fixture, pale daylight leaking through the small back window, soft warm tungsten ambient light filling the rest, dust in the air, damp domestic shadows, uneasy stillness, 35mm film grain, muted blue-gray and washed yellow palette.",

    "prompt": "Photorealistic cinematic still. [L05: A cramped modern Korean 옥탑방 (rooftop room) interior, dusty small window, worn sink, low table, pale daylight, damp muted domestic shadows.] C04O06 in a plain apron occupies the right-center of the frame, at three-quarter angle from the left, one hand gripping the apron hem, eyes fixed on the television at the far left. The lens emphasizes her serious expression, tightened jaw, and the tense hand at the apron hem through a thin veil of white kitchen steam in the left foreground. A blurred television edge, screen angled away, sits at the far left, its cold blue-gray glow brushing her cheek; pale daylight from the closed dusty window adds washed yellow highlights. A steaming pot with a slightly lifted lid sits in the foreground, P06 rests rinsed beside the sink, and a thin stream from the faucet falls into the basin in the background. Muted blue-gray and washed yellow palette, damp domestic surfaces, uneasy stillness.",
