L05B02
effective refs: (none) | mode=none | call=images.generate
plate_prompt_text used
This image is a film-production background plate reference for cinematic set design. It depicts an empty stage/background environment for storyboarding and production design, not a real-world event or person. Render it as concept art for a film set, with no live characters present.

Interior layout of a modest rooftop apartment's kitchen area under standing eye-level framing. A damp kitchen counter and sink run diagonally across the lower-left foreground. On the cooktop, steam vents upward from a boiling pot. In the background, thin pale daylight from a hazy sliding window mixes with the kitchen steam, flattening the space, while a TV in the adjacent room casts a faint residual glow.

Default-avoidance instruction: keep the generated space modest, narrow, and source-grounded; do not upgrade it into a spacious luxury, high-end minimalist, or bright expansive modern interior. Do not add adjacent areas or objects unless they are already requested by the per-bg prompt.

Low-to-mid height view peering through the half-open door of the bedroom, maintaining loose layout continuity and shared spatial tone with the kitchen base L05B02. A wet, dark red bloodstain spreads extensively across the bedroom floor, leading toward the window curtain at the end of the trail. Cold, night-blue darkness leaks from the window, broken by a faint amber spill from the adjacent room.

Eye-level wide layout of the rooftop bedroom, showing loose structural alignment and shared layout continuity with the blood-scene variant L05B04. The space is in a pristine, clean state: a neatly made bed with a spotless mattress and pillow sits against a bare and clean back wall. A calm window curtain hangs closed. Pervasive cold blue night light casts chilling shadows across the pristine floor, counterbalanced by a weak amber domestic glow from the doorway.
