Prompt
A before-and-after rooftop transformation. Left panel labeled 'EMPTY SPACE': a blank concrete rooftop corner with plain railing and no decor. Right panel labeled 'POP-UP CAFE': the same rooftop transformed into a photogenic seasonal café with a pink 'Sunset Sips' neon sign, branded cups, floral seating, a chalkboard menu board, and string lights. Preserve the viewpoint and structure while changing only the concept and styling.
