  "cover_prompt": "生成一张极简主义的抽象环境光晕（Ambient Aura）图片作为无字音乐专辑封面。画面的核心色彩组合与情绪倾向是：少年感的天空蓝与暮色暖橙之间的渐变张力——画面上半部分是开阔辽远的晴空蓝，向下逐渐沉入温厚的夕阳橙红，两者在画面中部形成一条柔软而发光的模糊边界，像一个人站在成长与归家之间的那个瞬间，向上是未来，向下是来处。画面完全由纯粹的色彩构成，采用极度的柔焦（Soft focus）和重度模糊效果（Blurred effect），使得不同颜色之间产生极其平滑、如丝绸般的无缝过渡。整体质感极致平滑细腻（Smooth texture），没有任何杂质。强烈要求：这是一张彻底抽象的现代色彩场（Color Field）作品，绝对不要出现任何具体的物体、几何图案或锐利的边缘！不需要任何胶片颗粒感！画面必须是无字封面，绝对不要生成任何文字、拼音或英文字母，不要生成人物轮廓！传达出一种极其平静、舒缓、现代且充满呼吸感的氛围。",

        "why": "'一个人扛'是华语苦情歌高频词汇，前半句'醒来灯全灭'有孤独画面感，后半句却用最烂大街的词接走了，功亏一篑；且'扛'字入声短促，旋律若为上扬则演唱极为别扭",

        "line": "你替我担心的，我都悄悄还回来",
        "why": "'还回来'的语义逻辑牵强——担心不是借物，无法归还；试图制造情感厚度却制造了语义漏洞，听众在感动之前先困惑了一秒，一秒足以断掉共鸣",
        "fix": "改换意象方向，例如'你替我担心的那些弯路，我都替你走直了'，或降低诗意度走口语路线'你怕我吃苦，我偷偷练硬了'"
