四座城市：3D文字雕塑重构

2x2 grid, do this for 4 iconic cities and their defining landmarks, transit elements, food, signage, and street details {
  Anchor: `[City Name] :: [City Identity / Mood (e.g., Tokyo Neon Transit / a man Époque / New York Grit)]::4`
  Morphology: `3D typographic sculpture spelling [City Name], letters constructed from a dense pile of city-specific objects, landmarks, street signs, transit parts, food packaging, architectural fragments, chaotic but legible assemblage, premium graphic design asset::3`
  Semantic Inference: `Objects must be unmistakably native to [City Name], culturally specific, historically appropriate, visually diverse but coherent::3`
  Material Physics: `Mixed material realism across metal, glass, painted concrete, paper, ceramic, plastic, worn textures, realistic contact shadows and interlocking forms shaping the letters::3`
  Illumination: `Studio lighting with subtle urban glow, clean isolated background, high contrast edge definition::2`
  Render Stack: `3D software render, front-facing or slight isometric, ambient occlusion, 8k, commercial poster finish::1`
  Negative: `[generic travel collage, wrong landmarks, illegible text, flat typography, floating pieces, busy background]::-1`
