Reframe this concept as: present a clear, side-facing isometric miniature 3D cartoon diorama of [CITY] along the [WATERFRONT]. The scene is a polished portrait image-oriented cross-section slice — the city is cut open like a museum specimen, mounted on a small raised diorama-aesthetic base that exposes the full stratigraphy from rooftop to riverbed. Above the waterline: a curated selection of [CITY]'s most signature waterfront elements — layered building facades in local architectural aesthetic, embankment promenade, bridges, trams or cyclists, warm gentle ambient illumination. Tiny stylized figures of residents in casual attire — walking, cycling, sitting at waterfront cafés (no facial details). The water surface is a polished glassy horizontal band — cartoon-stylized, slightly transparent, acting as the visual threshold between the two worlds. Below the waterline: the geographically honest submerged anatomy of [CITY]'s [WATERFRONT] — accurate foundation and piling types, real underwater infrastructure, sediment and substrate layers appropriate to this specific body of water, local aquatic life rendered in the same gentle cartoon aesthetic. Tiny stylized fish, slow-drifting particulate, refracted light shafts filtering down from the surface. The cross-section cut edge is razor-polished — pavement strata, foundations, soil layers, and underwater geology all simultaneously visible in the base wall, like a natural history diorama exhibit. Aesthetic: gentle polished textures, lifelike PBR materials, immersive ambient illumination. Color language: warm amber and golden tones above the waterline, cold teal-green and deep indigo below, blending at the water threshold. Ultra-polished, high-clarity 3D cartoon diorama aesthetic. Apply a polished solid [BACKGROUND COLOR] backdrop. At the top-center, display "[CITY]" in large powerful text, and place the waterfront name or a city landmark silhouette emblem below the text. All text must automatically match backdrop contrast. Layout: perfectly centered layout, square 1080x1080.
