云朵飘过太阳的天气图标

Create a 6-frame looping flat vector-style icon sprite sheet, 3 columns by 2 rows of equal 512x512 cells on a soft blue rounded-square background. Subject: a yellow sun with eight short rays behind one white rounded cloud. The sun's center stays fixed and its rays rotate 7.5 degrees per cell, so six cells complete a 45-degree repeat. The cloud drifts slowly to the right for three cells and back to the left for three cells. No gradients, no outlines, simple shapes, consistent palette. No grid lines, no numbers, no text.

生成 6 帧循环扁平矢量风图标精灵图，3 列 2 行，每格 512x512，柔和蓝色圆角方块背景。主体是一个带八道短光线的黄色太阳，前面是一朵白色圆润云朵。太阳中心固定，光线每格转 7.5 度，六格转完 45 度。云朵前三格缓慢向右飘，后三格向左飘回。没有渐变和描边，形状简单，配色一致。不要格线、数字和文字。
