彩色玻璃蝴蝶扇翅

Create a 6-frame looping sprite sheet, 3 columns by 2 rows of equal 512x512 cells on a dark charcoal background. Subject: a symmetrical stained-glass butterfly seen from directly above, with black lead lines and glowing cobalt, amber and ruby panes. Its body stays fixed at the center of each cell, and its wings flap by changing apparent width: fully open, three-quarter, half, narrow, half, three-quarter. The panes glow slightly brighter when fully open. Frame 6 returns to frame 1. No grid lines, no numbers, no text.

生成 6 幀迴圈精靈圖，3 列 2 行，每格 512x512，深炭灰背景。主體是從正上方看的對稱彩色玻璃蝴蝶，黑色鉛條線，發光的鈷藍、琥珀和寶石紅玻璃塊。身體固定在每格中央，翅膀靠視覺寬度變化來扇動：全開、四分之三、一半、窄、一半、四分之三。全開時玻璃略微更亮。第 6 幀接回第 1 幀。不要格線、數字和文字。
