黑板上起飞的粉笔火箭

Create a 6-frame looping chalk doodle sprite sheet, 3 columns by 2 rows of equal 512x512 cells on the same dark green chalkboard with faint eraser smudges. Subject: a simple white chalk rocket with a coral flame and three small stars. It hovers with a wobble in the center of each cell: leaning slightly left, level, leaning slightly right, level, leaning left, level, while the flame shape changes in every frame and the stars twinkle in turn. Rough chalk grain. Frame 6 returns to frame 1. No grid lines, no numbers, no text.

生成 6 帧循环粉笔涂鸦精灵图，3 列 2 行，每格 512x512，相同的深绿色黑板，有淡淡的擦痕。主体是一枚简单的白色粉笔火箭，配珊瑚色火焰和三颗小星星。它在每格中央悬停晃动：略左倾、水平、略右倾、水平、左倾、水平，火焰每帧变形，星星轮流闪烁。粉笔颗粒粗糙。第 6 帧接回第 1 帧。不要格线、数字和文字。
