    "scene_description": "凌晨时分一条被细雨浸湿的空旷柏油路，两侧路灯投下昏黄模糊的光晕，远处的城市天际线被浓雾完全吞没，路面反射着破碎的橘色光斑，一切都笼罩在潮湿沉闷的灰蓝色调中",
    "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：凌晨时分一条被细雨浸湿的空旷柏油路，两侧路灯投下昏黄模糊的光晕，远处的城市天际线被浓雾完全吞没，路面反射着破碎的橘色光斑，一切都笼罩在潮湿沉闷的灰蓝色调中。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": "歌曲核心情绪是凌晨独处的疲惫与认命感，72BPM的慢速R&B配合Cm调的忧郁氛围，适合用空旷夜景的复古风景流来传递那种'散场后无人收拾'的孤寂感。"
