  "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：极寒苍茫的冰青与深夜靛蓝交融叠压，中心透出一缕隐约的冷白光晕，如冰川深处封存的最后一点温度，边缘向外扩散为几近纯黑的深紫，传达出绝望与执念并存的悲凉情绪。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。",

        "fix": "保留春来的轻描淡写反衬失落，改为口语化意象收句，例：「春来了你的方向还是空的」或「春来了我还站在那片檐下」"
