撕裂海报边缘卷出的立体城市

🪽 “a torn lower poster edge curling outward into a real three-dimensional city reveal”
This makes the poster act like a physical threshold, not a flat image with scenery pasted onto it.
🧊 “match the paper’s torn edge to the city’s foreground: ceramic parapet, mosaic pavement, dust, and small debris”
The transition becomes believable because the printed world and the physical objects share one break line.
