Numbered circular black markers indicate specific zones and props.
Reconciled bedroom state transitions by keeping the spatial camera axis consistent through the bedroom door while varying the visible layout elements (#22, #25, #28) to match normal, ransacked, and bloody states.

A flat top-down 2D schematic floor plan of an institutional animal shelter interior corridor. Clean black outlines on a solid white background with flat pale gray and pale cyan fills. A long central walkway is flanked on both sides by narrow rows of wire cage stalls. Heavy metal doors are positioned at both ends of the central corridor. No 3D perspective, shading, or realistic rendering.
No production floor plan was available for L07. Created a functional basic corridor layout with wire cage rows to align with the director set brief.
