黑板上起飛的粉筆火箭

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 幀迴圈粉筆塗鴉精靈圖，3 列 2 行，每格 512x512，相同的深綠色黑板，有淡淡的擦痕。主體是一枚簡單的白色粉筆火箭，配珊瑚色火焰和三顆小星星。它在每格中央懸停晃動：略左傾、水平、略右傾、水平、左傾、水平，火焰每幀變形，星星輪流閃爍。粉筆顆粒粗糙。第 6 幀接回第 1 幀。不要格線、數字和文字。
