Prompt
Arrange urban-form samples in four equal columns: simplified pale-grey overhead maps above and corresponding black building silhouettes below. Consistent boundaries, direction, line weight and margins. Default fictional types: perimeter courtyard blocks, fine-grained lanes, parallel slabs and a point-building campus. For uploads, retain each sample's organization without merging sites. Match each upper/lower pair and do not invent obscured areas. Without verified common scale, compare form only, not density, area, age or development patterns. Landscape 3:2, no garbled text or watermark.
