天空不知，云朵知晓

一本极具概念性的书籍封面，标题为《天空不知，云朵知晓》。背景为强烈近乎电光的青蓝色，中央有一个巨大的云朵剪影被镂空，露出第二层深皇家蓝。在云形内部，还有一个更小、精致的淡天蓝色云朵剪影。构图简洁而超现实，标题以极细的白色无衬线字体置于右上角，宛如一幅视觉诗歌，极简、震撼，适合画廊展出。

A bold, conceptual book cover for "What the Sky Doesn't Know, the Clouds Know". Background is an intense, almost electric cyan blue. In the center, a large cloud silhouette cut out, revealing a second layer of deep royal blue. Inside that cloud shape, there is a much smaller, delicate cloud silhouette in pale sky blue. The composition is simple but surreal. Title in thin white sans-serif letters, very small, at the top right. Feels like a visual poem. Minimalist, striking, gallery-worthy.
