Vocals are central and clear.; Structure: Intro - Verse - Chorus - Verse - Bridge - Chorus - Outro; Language: Mandarin; Highlight: the dramatic dynamic swell from a sparse verse to a lush, string-filled chorus",

  "cover_prompt": "生成一张无字音乐专辑封面。风格严格参照 20 世纪 Color Field Painting（色域绘画），如 Mark Rothko 晚期作品的色层叠压逻辑与 Helen Frankenthaler 的浸染法（soak-stain technique）。画面的核心色彩与情绪：旧象牙白与深灰蓝之间宽阔而缓慢的渗透地带，中央有一层极浅的暖黄浮在表面，像被压了很久的纸张在光线下透出的底色，既不明亮也不黯淡，只是安静地泛着一种无处安放的温度，四周被冷蓝灰缓缓收拢，像一次无声的告别。技法要求：色彩之间的过渡必须模拟颜料在未上浆的粗纹棉布（raw cotton canvas）上自然渗透、晕开的效果，边界柔软但保留颜料浓度不均匀造成的自然深浅变化（pigment pooling）。画面需要呈现真实画布的编织肌理（woven canvas texture），局部可见稀薄处透出的底布纹路。整体色调偏低饱和、微微发灰（muted, desaturated palette），避免荧光感和数字渐变的均匀平滑。绝对禁止：任何文字/字母/拼音、人物或人物轮廓、具象物体、几何图案、锐利边缘、胶片颗粒滤镜、3D渲染质感。",
