    "scene_description": "一条被浓雾完全吞没的城市高架桥，路灯发出昏黄的光晕却照不穿白茫茫的虚空，远处的建筑轮廓像水墨画般层层淡去，地面反射着潮湿的冷光，整个世界仿佛被按下了静音键",
    "cover_prompt": "生成一张拍立得（Polaroid）风格的无字版音乐专辑封面。画面描绘的是：一条被浓雾完全吞没的城市高架桥，路灯发出昏黄的光晕却照不穿白茫茫的虚空，远处的建筑轮廓像水墨画般层层淡去，地面反射着潮湿的冷光，整个世界仿佛被按下了静音键。整体画面必须呈现真实拍立得相片的质感：略微过曝的柔和光线、轻微偏色的复古色调、自然的暗角和柔焦边缘、细腻的胶片颗粒感。色彩是褪色、怀旧的暖色调，仿佛一张被遗忘在抽屉里多年的即时成像照片。强烈要求：画面必须是纯粹的风景，绝对不要出现任何人物、人影、手或脸！绝对不要生成任何文字、字母、歌名或水印！保持空灵、孤独和冥想的氛围。",
    "selection_reason": "歌曲核心情绪是迷失与孤独的漂泊感，浓雾中的城市景观能精准传达这种被隔绝、看不清前路的茫然，复古风景流的空旷与怀旧质感与62BPM慢速R&B的沉郁氛围高度契合。"
