#1 living dining area, #2 kitchen nook, #3 bedroom, #7 front door, … (+10 more)
A flat 2D schematic top-down floor plan of a small South Korean rooftop apartment, clean vector line style on off-white background with pastel color-coded room fills. The apartment has a central living dining area filled pale yellow, a small kitchen nook in the northwest filled pale green, a bedroom on the east filled pale blue, a compact bathroom filled pale cyan, and an entry alcove filled pale beige. Includes symbols for sliding windows on the west and east walls, a front door, bedroom door, dining table, kitchen counter with sink, and a bed in the bedroom. Circular markers with numbers label the zones and fixtures. No text, no perspective, no 3D rendering.
Numbered marker contract: draw circular markers with EXACTLY the listed marker numbers below. Preserve the exact non-consecutive marker numbers listed below. Do not renumber, do not omit listed markers, and do not invent additional marker numbers.
#1 living dining area — area — central and west main room, pale yellow fill
#2 kitchen nook — area — northwest corner connected openly to living dining area, pale green fill
#3 bedroom — area — east room behind interior door, pale blue fill
#7 front door — opening — south wall of entry alcove, showing swing arc
#8 bedroom door — opening — east wall of living area opening into bedroom
#10 living sliding window with curtains — opening — west exterior wall of living area with curtain line
#11 bedroom sliding window with curtains — opening — east exterior wall of bedroom with curtain line
#12 dining table — furniture — center of living dining area
#18 kitchen counter with sink and cooktop — furniture — north wall of kitchen nook
#20 bed or floor mattress — furniture — north side of bedroom
#22 body and red stain zone — plot_device — bedroom floor beside bed, flat red marker
#23 footprint trail — plot_device — from bedroom floor leading through bedroom door
#25 red circular wall mark in bedroom — plot_device — north bedroom wall surface
#28 toppled chair or fallen cushion — furniture — near dining table on living floor
For plot_device entries, draw only an abstract floor-plan marker/zone cue, not a literal entity instance or action.

#1 corridor path, #2 heavy metal doors, #3 oblique wire cages, #4 concrete walls, … (+1 more)
A flat 2D schematic top-down floor plan of an institutional animal shelter corridor, clean vector line style on a pale gray background. The plan shows a long central hallway corridor flanked on both sides by rows of wire cages drawn with neat parallel metal grid symbols. Heavy metal door swings are shown at both ends of the corridor. Solid concrete walls enclose the layout with simple single-weight outlines. Circular markers with numbers label the cages, doors, and corridor space. No perspective, no 3D effects, no text.
Numbered marker contract: draw circular markers with EXACTLY the listed marker numbers below. Preserve the exact non-consecutive marker numbers listed below. Do not renumber, do not omit listed markers, and do not invent additional marker numbers.
