松饼上慢慢化开的黄油

Create a 6-frame food animation sprite sheet, 3 columns by 2 rows of equal 512x512 cells. Subject: the same realistic stack of three golden pancakes on a white plate on a pale wood table, shot from the same 45-degree angle in every cell. A square of butter on top melts in stages: firm with sharp corners, softened corners, sliding, half melted, small pool, then soft mound leading back to the start. Thin steam rises and changes shape. Plate, pancakes and light never move. No grid lines, no numbers, no text, no logos.

生成 6 帧美食动画精灵图，3 列 2 行，每格 512x512。主体是相同的三层金黄松饼，放在浅木桌上的白盘里，每格都是同样的 45 度机位。顶上的方块黄油分阶段融化：边角锋利、边角变软、开始滑动、半融、小摊融液，再到一小团接回起点。细蒸汽上升并变形。盘子、松饼和光线不动。不要格线、数字、文字和标志。
