  "cover_prompt": "生成一张极简主义的几何光影艺术图片作为无字音乐专辑封面。画面的核心是：一级台阶边缘的极简侧面轮廓，以极度柔焦方式呈现，仅保留一条微微发光的水平弧线，颜色为温暖的奶油白与浅金黄，悬浮于从明媚柠檬黄过渡至天空粉蓝的水彩渐变背景之中，弧线下方投下一片极淡的椭圆形阴影，仿佛某个踮起脚尖的瞬间被定格。画面必须展现出微妙的高级材质肌理，特别是类似水彩晕染（Watercolor texture）或粗糙艺术纸张的触感。整体构图极度克制、留白（Minimalistic composition），注重光与影的柔和交错（Light and shadow interplay）。强烈要求：画面必须保持极致的安宁与静谧（Calm and serene），除了基础的、柔焦的简单几何图形（如模糊的圆、半透明的方块或柔和的线条）外，绝对不要出现任何复杂的现实物体、风景或人物！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！绝对不要生成人物轮廓。传达出一种充满诗意、呼吸感与冥想空间的视觉感受。",
