    "scene_description": "清晨时分，一条被乳白色浓雾完全吞没的乡间泥路向远方无限延伸，两侧是模糊的、泛着暗金色光泽的枯黄草甸，地平线消融在一片蜜桃色与铅灰色交汇的天际光晕里，空气中仿佛凝结着露水和微凉的呼吸",
    "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：清晨时分，一条被乳白色浓雾完全吞没的乡间泥路向远方无限延伸，两侧是模糊的、泛着暗金色光泽的枯黄草甸，地平线消融在一片蜜桃色与铅灰色交汇的天际光晕里，空气中仿佛凝结着露水和微凉的呼吸。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": "歌曲以温柔的吉他指弹和男声讲述离家漂泊对亲人的思念，情绪内核是'温暖却遥不可及的归属感'，复古空旷风景模板的孤独感和回忆质感与BPM 70的民谣曲风、怀旧忧伤又带希望的Mood高度吻合。"
