8-bit 金幣原地旋轉

Create a 6-frame 8-bit pixel art sprite sheet, 3 columns by 2 rows of equal 512x512 cells on a solid deep purple background. Subject: one gold coin with a simple star emboss, spinning around its vertical axis at the center of each cell. Widths in sequence: full face, three-quarter, narrow, thin edge line, narrow reversed, three-quarter reversed. Same height and center in all cells. Hard blocky pixels, 6-color palette with one small white sparkle. Frame 6 returns to frame 1. No grid lines, no numbers, no text.

生成 6 幀 8-bit 畫素風精靈圖，3 列 2 行，每格 512x512，純深紫色背景。主體是一枚帶簡單星形浮雕的金幣，在每格中央繞豎軸旋轉。寬度依次是：正面、四分之三、窄面、一條細邊、反向窄面、反向四分之三。每格高度和中心一致。方塊畫素邊緣銳利，6 色調色盤，配一個白色小閃光。第 6 幀接回第 1 幀。不要格線、數字和文字。
