    "scene_description": "夜晚城市街头，积水路面倒映着霓虹碎光，一面巨大的玻璃幕墙将天空切割成不规则碎片，玻璃上附着一层薄雾，模糊的女性侧影贴近玻璃表面，城市灯火在玻璃内外叠影，整体色调为深蓝、冷紫与暖橙霓虹的对比，胶片颗粒感，疏离而迷幻",
    "cover_prompt": "Rainy night city street with neon reflections shattered across wet pavement, a massive glass curtain wall fragmenting the dark sky into irregular shards, thin condensation mist clinging to the glass surface, a blurred female silhouette pressing close to the glass from outside looking in, layered city lights creating double exposure effect inside and outside the glass, deep navy and cold violet tones contrasted with warm amber neon streaks, analog film grain texture, cinematic composition in square format, no legible text, no clear faces, urban isolation and longing atmosphere, hyperrealistic glass reflections, melancholic and sultry mood",
    "selection_reason": "歌词以玻璃城市为贯穿意象，门窗钥匙站台构成疏离叙事，玻璃幕墙的反射与透而不通的特质在视觉上完美呼应歌词核心张力，夜城霓虹与冷调光影契合R&B灵魂乐的都市忧郁气质"
