  "cover_prompt": "生成一张现代平面设计（Modern graphic design）风格的几何艺术图片作为无字音乐专辑封面。画面的核心是：深紫黑色背景上，数条从画面中央向外放射延伸的锐利霓虹线条，颜色在炽热的橙红与电光品红之间交替渐变，线条边缘带有轻微的发光晕染（Glow effect），中心汇聚处形成一个高亮的爆发点，如同信号弹在夜空中炸裂的瞬间。采用纯粹的数字矢量图形（Vector art）媒介，质感极致平滑干净（Smooth and clean textures），绝对没有任何画笔笔触、水彩晕染或写实肌理。通过线条的排列、交错和高对比度色彩，创造出类似欧普艺术（Op Art）的视觉错觉，赋予画面极强的视觉动感（Sense of movement）和空间纵深感（Depth）。强烈要求：这是一张纯数字生成的抽象几何图形作品，绝对不要出现任何具象的自然风光、人物、动物或实体物品！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！传达出精准、充满秩序感且极具律动（Groove）的现代视觉效果。",
