会跑的小屋踩上本垒板
一栋长腿小屋冲刺踩垒，透明通道出图，拿来就能抠进任何版面。
✍️ 关键变量是 alpha = 0 后面那串否定：不是白底、不是彩色底、没有棋盘格，三条排除叠在一起才逼出真透明。接触阴影只写“接触处最深、向外衰减”，抠出来贴到别的版面也不会飘。

Surreal miniature sports photography in bright afternoon light, crisp focus across the whole scene, 16:9 wide composition. Side three-quarter view of a small pitched-roof cottage sprinting on two sturdy legs: the front shoe is planted squarely on a blank white home plate, the back leg kicks behind in mid-stride, and the front door and windows ride along on its moving walls. Give it cream plaster walls, a brown shingle roof, a blue front door and a white-and-red running shoe on each foot. Under the cottage and the plate, add a soft semi-transparent black contact shadow in the alpha channel, darkest where things touch and fading outward.
Deliver it as a real alpha channel on a fully transparent background (alpha = 0): no white fill, no colour fill, no checkerboard pattern. Keep the cottage and plate completely inside the frame with clear transparent margin on every side, nothing cropped or touching the borders.
No lettering anywhere. The plate is plain white rubber without a logo, the walls carry no house numbers or signs, and there are no stadium signs, scoreboards, uniforms or background surfaces.

超现实微缩运动摄影，午后明亮光线，全画面对焦清晰，16:9 宽构图。侧前四分之三视角：一栋小巧的坡顶小屋用两条结实的腿奔跑，前脚稳稳踩在一块空白的白色本垒板上，后腿在跨步中向后踢起，前门和窗户随着移动的墙体一起晃动。奶油色灰泥墙、棕色木瓦屋顶、蓝色前门，每只脚上一双白底红边跑鞋。小屋和本垒板下方，在 alpha 通道里加一层柔和的半透明黑色接触阴影，接触处最深，向外渐隐。
以真实 alpha 通道输出，背景完全透明（alpha = 0）：不要白底，不要彩色底，不要棋盘格图案。小屋与本垒板完整落在画面内，四周留出透明边距，不被边框裁切或贴边。
画面中不出现任何文字：本垒板是无标志的纯白橡胶，墙上没有门牌号或标牌，也没有球场标识、记分牌、球衣或背景表面。
