A compact rooftop apartment living room in a calm daytime state, 35mm cinematic still aesthetic, eye-level camera about 1.6m high, slight wide angle around 28mm, single instant, no collage. Frame the modest room so the west wall television sits on the left side facing inward, emitting a cold blue-gray glow with no readable screen text, while pale daylight enters from a small window on the opposite side and mixes with a faint kitchen steam haze. Along the back north wall is a narrow kitchenette: aged off-white lower cabinets, a small stainless sink, a compact two-burner stove, a simple metal pot on the stovetop, a worn backsplash with subtle grease stains, and a short counter with ordinary kitchen items kept tidy. In the center is a small rectangular dining table with mismatched wooden chairs, a few plain teacups on the tabletop, and slightly scuffed edges. Toward the south side is a shallow entry vestibule with a dull metal exterior door, a low shoe area, and everyday footwear storage kept orderly. The walls are old plaster, uneven and lightly cracked, painted warm gray-beige with faint discoloration near corners; the floor is worn vinyl or laminate in muted brown-gray with dull scuffs; the ceiling is low, flat, off-white plaster with a simple flush ceiling light and slight age staining. Add a slim floor lamp near the window, turned off or very faint, contributing to the lived-in silhouette. Overall palette is modest beige, gray, faded wood, and cold blue television spill, with soft natural daytime illumination, quiet dust in the air, no disturbed surfaces, no aftermath marks, no blood, no broken glass, no weapons, and no action.",

The floor is made of narrow worn brown floorboards with scratches, dust in the seams, dull varnish, and cold gray reflections; on the floor near the bed is a dark red pooled stain and a trail of red-brown footprint-like marks leading toward the curtained north window, presented as old staining only, with no gore, no bodies, no action. The low flat ceiling is stained plaster with a simple small round ceiling fixture switched off or barely glowing, leaving the room dim. A single narrow bed stands along one side wall with a thin rumpled gray blanket, faded pillow, and cheap metal or laminate frame; beside it are a small low bedside box, a plastic basin or storage tub, a few soft clutter items, and dust. The north wall has a closed window fully covered by heavy faded beige-gray curtains, the fabric hanging still and opaque, with a slight dirty hem near the floor. The south doorway is open at the edge of the composition, showing only a sliver of the adjoining living space as a weak cold blue-gray television spill that grazes the doorframe and floorboards.

One surveillance screen shows a dark, low-quality black-and-white image of an empty store aisle, grainy and dim, with no people, no violence, no weapons, no blood, no broken glass.

A modern open-plan detectives office with no windows, viewed at eye level around 1.6m with a slight wide angle 28mm lens, 35mm cinematic still aesthetic, one quiet instant. The frame centers on the right-side duty desk area under harsh green-white fluorescent ceiling light. Dull gray painted drywall surrounds the room, slightly scuffed and matte, with darker gray baseboards and a muted institutional palette of gray, off-white, black plastic, beige paper, and cold green highlights. The floor is worn gray vinyl composition tile with subtle seams, dull reflections, dust in corners, and a clear circulation path running from a bottom-center rear door toward the middle of the office. The ceiling is a low suspended acoustic tile grid with rectangular recessed fluorescent troffer fixtures, flat and clinical, casting even shadowless light. At the rear center is a plain interior door leading to a station corridor, with a narrow wired-glass vision panel and metal push plate; keep the corridor dim and generic. On the right side, a rectangular duty desk holds an inward-facing computer monitor showing an abstract digital street map with English-only interface text and a single red coordinate marker, plus a keyboard, mouse, scattered forms, file folders, pens, a desk phone, and coffee stains. A visitor chair sits across the desk on the near side. In the background, include additional workstations with dark office chairs, low partitions, filing cabinets, cork boards with English-only notices, fluorescent-lit shelves, and a small coffee counter with a compact machine and paper cups. No blood, no broken glass, no weapons, no action, no structural disturbance; only normal desk clutter, worn surfaces, dust, and cold fluorescent stillness.",

The room has dull matte gray painted walls with subtle scuffs, pin marks, smudged corners, and worn baseboards; a gray speckled vinyl composite tile floor with faint mop streaks and flattened chair-wheel tracks; a low suspended acoustic tile ceiling with metal grid lines, rectangular vents, sprinkler heads, cable trays, and harsh green-white fluorescent troffer fixtures.

Keep a clear circulation path from the door into the middle of the room. In the left-center foreground stands a rectangular laminate desk with metal legs, cluttered with glossy enlarged case photographs showing only empty rooms, numbered markers, paperwork, sticky notes, folders, pens, pencils, a ruler, a stapler, and paper clips; no visible bodies, no blood, no weapons, no broken glass. On the right side is a duty desk facing inward, holding a computer monitor angled toward the room; the screen displays an English-only gray-blue maritime map interface with contour lines and a single red coordinate marker, plus a keyboard, mouse, scattered forms, a desk phone, and a black task lamp.
