    "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：凌晨时分一片广袤无垠的盐湖，湖面如镜面般倒映着从深蓝渐变至灰紫的天穹，薄薄的雾气紧贴水面缓缓游移，远处地平线上残留一抹极淡的、即将熄灭的暖橙色光晕，四周寂静得仿佛时间已经彻底停止流动。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BPM72的慢速节奏配合breathy人声营造出极致的孤寂与怀旧氛围，盐湖镜面的空旷与凝滞感完美映射深夜失眠时温度渐散的情绪内核，选择复古空旷风景流最为契合。"
