L01B01path_depthnone
placeholder_dry_run appendix
A wide-angle, low eye-level view of a damp, muddy forest path receding into a cold blue-gray twilight haze in the center background. Overgrown dark green bushes scrape the left and right frame edges, their wet leaves catching specular highlights from the faint low dusk light filtering through dense, towering trees.

placeholder_dry_run appendix
L02B01alley_corridornone
placeholder_dry_run appendix
A static wide-angle shot looking down a long stretch of damp, dark pavement toward a central rough utility pole. Grimy, damp brick urban alley walls angle inward, framing the space like a dark tunnel. A weak amber streetlight pools directly around the utility pole's base, contrasting with cold blue-black shadows along the alley edges.

placeholder_dry_run appendix
L03B01forensic_corenone
placeholder_dry_run appendix
A flat ground-level wide shot of an outdoor crime scene under desaturated, overcast flat daylight. Stretched yellow police line tape is visible in the background in broken strips, with its printed warning side facing the camera, while open forensic equipment cases rest on the damp soil nearby under cold gray highlights.

placeholder_dry_run appendix
L04B01parapet_to_bulkheadnone
placeholder_dry_run appendix
A low-angle view beside a damp, rough-textured concrete wall of a villa rooftop structure. Dense, cold bluish predawn fog swallows the exterior space, layering thin mist. Muted amber light leaks from the fogged glass of a small window, forming a warm glowing square, with the wet top edge of the concrete wall guiding the eye toward it.

placeholder_dry_run appendix
L04B02parapet_to_bulkheadnone
placeholder_dry_run appendix
A high oblique overhead wide-angle view of an old, sun-bleached villa concrete rooftop yard. The dry, cracked concrete surface contains a small stair bulkhead, a metal AC unit, a rounded water tank, and a laundry line with simple wooden posts. Crowded neighboring rooftops are visible in the far background under a dry, pale beige-gray daylight palette.

placeholder_dry_run appendix
L04B03parapet_to_bulkheadnone
placeholder_dry_run appendix
An ankle-height wide view of the old villa rooftop yard at night. A closed iron entrance door on the concrete stair bulkhead looms in the upper-center background against a background of damp concrete. The severely underexposed, cold blue-black night atmosphere is cut by a muted amber side light, casting a sharp-edged long shadow diagonally across the concrete scattered with dry, dead leaves.

placeholder_dry_run appendix
L05B01fp_l05_01entry_to_bedroomnone
placeholder_dry_run appendix
An eye-level wide shot from the living area of a compact rooftop apartment looking toward a clean, empty floor in the center. In the background, sliding window curtains are pulled apart to both sides of the window, revealing pale, clean glass. Washed dawn daylight filters into the room, creating a pale blue, spotless interior.

placeholder_dry_run appendix
L05B02fp_l05_01entry_to_bedroomnone
placeholder_dry_run appendix
A standing eye-level view of a modest rooftop apartment's kitchen area. 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 television in the adjacent room casts a faint residual glow.

placeholder_dry_run appendix
L05B03fp_l05_01entry_to_bedroomnone
placeholder_dry_run appendix
A view into the rooftop bedroom interior through a half-open wooden door gap. The dim interior is filled with cool dusk-blue ambient light, revealing an unsettled bed, a scattered chair, and a rough red wall mark painted in a coarse circle on the inner bedroom wall.

placeholder_dry_run appendix
L05B04fp_l05_01entry_to_bedroomnone
placeholder_dry_run appendix
A low-to-mid height view peering through the half-open door of a dark bedroom. A wet, dark red bloodstain spreads extensively across the wood floor, leading toward the window curtain at the far end of the room. Cold, night-blue darkness leaks from the window, broken by a faint amber spill from the adjacent room.

placeholder_dry_run appendix
L05B05fp_l05_01entry_to_bedroomnone
placeholder_dry_run appendix
An eye-level wide layout of the rooftop bedroom 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 over the window. Pervasive cold blue night light casts chilling shadows across the pristine floor, counterbalanced by a weak amber domestic glow from the doorway.

placeholder_dry_run appendix
L06B01road_diagonalnone
placeholder_dry_run appendix
A bright, sunlit wide view of a dry, open coastal road stretching diagonally. A weathered steel guardrail runs horizontally as lateral streaks, backed by a hazy, breezy coastal horizon under clear, slightly desaturated daylight.

placeholder_dry_run appendix
L06B02road_diagonalnone
placeholder_dry_run appendix
A wet asphalt road edge running horizontally under cold, wind-blown sea fog. Dense night fog provides a thin background separation from the deep blue-black sea under cold night ambient light, replacing the clear daytime horizon.

placeholder_dry_run appendix
L07B01fp_l07_01kennel_recessionnone
placeholder_dry_run appendix
An eye-level narrow view of an animal shelter corridor under cold blue-white fluorescent lighting. Oblique wire cages, heavy metal doors, and cold concrete walls recede into a soft, out-of-focus metallic blur.

placeholder_dry_run appendix
L08B01awning_upwardnone
placeholder_dry_run appendix
An exterior view of a commercial storefront under an overhanging architectural awning. The scene is enveloped in cool, muted early morning shade, with a security CCTV camera visible on the underside of the ceiling awning, and a faint, warm amber glow spilling outward from the mart's interior through the glass storefront window.

placeholder_dry_run appendix
L08B02awning_upwardnone
placeholder_dry_run appendix
An exterior wide layout of a busy evening street next to a commercial storefront. A bright storefront with clean fluorescent lighting runs parallel along the right frame edge, while a glowing neon sign casts smeared amber-red light across the building front. A busy evening street streaks into a neon blur in the background.

placeholder_dry_run appendix
L09B01aisle_viewnone
placeholder_dry_run appendix
An interior wide view of a supermarket aisle, boxed in by tight vertical lanes of product displays with rows of red packaging showing blurred labels. Stark white overhead fluorescent lights mix with a deep dusk-blue light spill from the distant entrance.

placeholder_dry_run appendix
L10B01monitor_axisnone
placeholder_dry_run appendix
A small administrative office interior. A shared admin desk in the foreground holds a dark monitor displaying a hard-to-read security feed. The environment is illuminated by a mix of dull, flat fluorescent ceiling lights and a cold blue glow radiating from the screen, with the office door located in shadow behind.

placeholder_dry_run appendix
L11B01fp_l11_01stair_risenone
placeholder_dry_run appendix
A narrow rooftop stairwell landing. A dark, stained, damp concrete wall flattens the landing space. Cold blue night light washes over the landing steps, while a weak amber glow from an unseen doorway grazes the side.

placeholder_dry_run appendix
L12B01bench_to_oceannone
placeholder_dry_run appendix
A desolate coastal bus stop at night. A stationary wooden bench cuts horizontally through the lower frame next to an empty seaside road. A vast, blue-black moonless sea stretches into the background, partially veiled by low, drifting cold coastal fog under thin dark vertical posts.

placeholder_dry_run appendix
L13B01desk_surface_axisnone
placeholder_dry_run appendix
A low-angle view of a detective office desk. The worn front lip of the scuffed desk crosses the frame, with out-of-focus scattered paper folders and crime photographs implied as a blurred strip of pale edges. Sterile blue-gray fluorescent lighting washes the room as rows of vacated desk sides recede in the blur.

placeholder_dry_run appendix
L13B02desk_surface_axisnone
placeholder_dry_run appendix
An institutional police duty office interior. The front edge of a solid police duty desk forms a dark horizontal strip along the bottom edge. The shallow background reveals a dim night-duty office environment, flattened by cold fluorescent overhead lights.

placeholder_dry_run appendix
L14B01frontage_viewnone
placeholder_dry_run appendix
An exterior wide shot of an institutional concrete building frontage under cool, desaturated daylight. Double glass doors stand directly behind, with a faint amber interior spill visible through the glass. Empty concrete pavement recedes toward the entrance from the street.

placeholder_dry_run appendix
L15B01cubicle_diagonalnone
placeholder_dry_run appendix
An interior view of a modern PC room under stale fluorescent white overhead lights. Rows of quiet cubicles and partition sides recede diagonally into the background, with a cold cyan monitor glow visible along the lower foreground edge.

placeholder_dry_run appendix
L16B01harbor_depthnone
placeholder_dry_run appendix
A deserted coastal harbor during post-storm dusk. Slick wet cobblestones of the harbor edge occupy the lower frame, with the quay line receding from the lower left toward the background under dense, heavy sea fog and cold blue-gray dusk lighting.

placeholder_dry_run appendix
L17B01deck_depthnone
placeholder_dry_run appendix
A wide view on the deck of a small fishing boat under cold blue twilight. The layout features a chipped, rusted outer rail at the edge of the wet deck, with a dark, empty open sea stretching in the background, faintly lit by a thin amber-red sunset trace on the horizon.

placeholder_dry_run appendix
L18B01doorway_to_helmnone
placeholder_dry_run appendix
An interior view of a cramped fishing boat wheelhouse. The space is heavily shadowed in cold blue-black tones, with a narrow, muted red sunset glow bleeding through the dirty front window. The light casts directional shadows across the steering wheel and helm console, seen from the rear doorway.

placeholder_dry_run appendix
L19B01fog_wall_axisnone
placeholder_dry_run appendix
A vast open ocean at dusk. A towering dark fog wall rises in the middle-center background as an opaque vertical mass of churning mist. The dark, damp sea surface ripples in the low foreground, reflecting muted amber sunset streaks under a cold blue dusk sky.
