    "scene_description": "一条笔直延伸至地平线的废弃铁轨，两侧是枯黄到近乎透明的野草，天空被厚重的灰紫色云层完全压住，远处地平线透出一缕即将熄灭的暗金色余晖，像一天中最后一口叹息，铁轨表面反射着湿润而冰冷的微光",
    "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：一条笔直延伸至地平线的废弃铁轨，两侧是枯黄到近乎透明的野草，天空被厚重的灰紫色云层完全压住，远处地平线透出一缕即将熄灭的暗金色余晖，像一天中最后一口叹息，铁轨表面反射着湿润而冰冷的微光。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": "歌曲围绕离别、站台、无法回头的成长主题，情感基调是深沉的孤独与怀旧，适合用空旷的自然风景来隐喻那种一去不返的寂寥感，拍立得的褪色质感恰好呼应'旧'的时间维度。"
