    "scene_description": "浓雾完全吞没的一条锈迹斑驳的铁轨，向远方延伸却在灰白色的雾气中彻底消失不见尽头。铁轨两旁是枯黄倒伏的野草，天空是一整片均匀压抑的铅灰色，没有太阳也没有地平线，只有雾中隐约透出的一丝冷蓝色微光。整个画面弥漫着再也无法抵达的绝望宁静。",
    "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：浓雾完全吞没的一条锈迹斑驳的铁轨，向远方延伸却在灰白色的雾气中彻底消失不见尽头。铁轨两旁是枯黄倒伏的野草，天空是一整片均匀压抑的铅灰色，没有太阳也没有地平线，只有雾中隐约透出的一丝冷蓝色微光。整个画面弥漫着再也无法抵达的绝望宁静。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'再也无法联系到的人'的失落与怀念，铁轨消失在浓雾中的意象隐喻了那条断裂的连接——你知道它曾经通向某处，但现在只剩下看不见尽头的空茫。复古风景流的孤独空旷感与BPM 72的缓慢忧伤完美契合。"
