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.

A medium standing eye-level view of a cramped rooftop apartment kitchen and living space. A damp kitchen counter and sink run diagonally across the lower-left foreground. In the background, steam vents upward from a boiling pot on a cooktop. Further back, thin pale daylight from a hazy closed sliding window mixes with the kitchen steam under flat gray-blue ambient tones, creating a flat, narrow room layout.

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.

A low-to-mid height view peering through a half-open bedroom door. A wet, dark red bloodstain spreads extensively across the bedroom floor, leading toward the window curtain at the far end of the trail. Cold, night-blue darkness leaks from the window, broken by a faint amber spill from the adjacent room, keeping a loose structural alignment with the door and window layout.

An eye-level wide view from the bedroom doorway looking at a bedroom restored to a clean state. A neatly made bed with a spotless mattress and pillow is squared to the room, with a bare, clean wall above it. Pervasive cold blue night light casts chilling shadows across the pristine floor, counterbalanced by a weak amber domestic glow, preserving loose structural alignment with the door and window axis.
