Create a 16:9 Shanghai-themed paper-cutting and layered paper-craft artwork as a rich panoramic city collage. Split the scene between warm daytime old Shanghai on the left and glowing nighttime modern Shanghai on the right, connected by sweeping layered paper ribbons and ornate Art Deco borders. Include the Oriental Pearl Tower as a central vertical anchor, the Bund-style historic waterfront architecture, boats on the Huangpu River, magnolia flowers, xiaolongbao baskets, a crab dish, old lane houses, neon restaurant streets, lanterns, small street stalls, vintage cars, river reflections, the Lujiazui skyline, the Shanghai Tower, and a large decorative Chinese title reading `上海`. Use stacked paper layers, clean cut edges, embossed details, soft shadows, warm-to-cool color contrast, and a polished festival-poster composition. Keep the work original and decorative rather than a literal tourist map. Avoid real brand logos, copied poster art, inaccurate landmark labels, misspelled Chinese signage, cluttered unreadable text, isolated unsupported paper parts, broken paper edges, and watermarks. Output a high-quality 16:9 image ready for GPT Image 2.
