Emergency Entrance Block

12x6m single-storey emergency department front on the 2m grid, roof at exactly 3m with a parapet, wide sliding ambulance doors, illuminated red department sign band and a glazed triage bay, flat side walls on the footprint edges; excludes the entrance canopy.

风格：low-poly, flat-shaded vertex colors, no textures, single shared material, so any set of these merges to one draw call; shares palette and scale with its kit
