8-bit 金币原地旋转

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 帧 8-bit 像素风精灵图，3 列 2 行，每格 512x512，纯深紫色背景。主体是一枚带简单星形浮雕的金币，在每格中央绕竖轴旋转。宽度依次是：正面、四分之三、窄面、一条细边、反向窄面、反向四分之三。每格高度和中心一致。方块像素边缘锐利，6 色调色板，配一个白色小闪光。第 6 帧接回第 1 帧。不要格线、数字和文字。
