    "scene_description": "黄昏最后一缕光线斜斜穿过一片无边际的枯黄草原，地平线上是从淡橘粉渐变到灰蓝的天空，远处几棵瘦削的白桦树在逆光中拖出极长的影子，空气中有金色的微尘在缓慢漂浮，整个世界像是被按下了暂停键，温暖正在一点点从画面边缘撤退",
    "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：黄昏最后一缕光线斜斜穿过一片无边际的枯黄草原，地平线上是从淡橘粉渐变到灰蓝的天空，远处几棵瘦削的白桦树在逆光中拖出极长的影子，空气中有金色的微尘在缓慢漂浮，整个世界像是被按下了暂停键，温暖正在一点点从画面边缘撤退。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": "歌曲核心情绪是温暖正在消逝的怅然与不舍，BPM 64的慢速钢琴叙事配合男声从气声到胸声的爆发，带有强烈的回忆感和孤独感，最适合用空旷的自然风景来隐喻这种'余温渐散'的情绪状态。"
