购物车里推着一整扇窗户
篮子里唯一的商品是一扇带木框的窗，价签空白得什么都没写。
✍️ 这条图的分寸感在两种材质的对比上——磨砂钢丝偏冷偏硬，松木窗框偏暖偏软，挂牌留白就是不让任何一种材质抢戏。购物车本身只是个容器，真正的主角是窗。

Set against a fully transparent background - alpha equals zero, never white, never coloured, no checkerboard pattern, a genuine alpha channel throughout - a shopping cart occupies a 1:1 square frame. Inside its brushed-steel wire basket stands the cart's only cargo: a single freestanding window, framed in wood with the grain showing clearly, glass panes left clear, held upright rather than lying flat. A string ties a small blank paper tag to the frame, nothing written on it.
Clean, precise edges run through the cart's grid wires, its small caster wheels, and the window's muntin bars, all picked out under soft, even studio light that sets muted steel grey against warm pine and the tag's pale blankness. Where cart meets ground, a soft, semi-transparent contact shadow sits in the alpha channel, deepest at the wheels and fading outward, while clear margin wraps cart and window on every side, nothing touching or cropped by the frame's edge.

整个画面架在完全透明的背景之上——alpha值为零，不是白色也不是任何颜色，没有棋盘格，全程使用真实的alpha通道——一辆购物车以1:1正方形构图占满画框。它那只不锈钢磨砂网篮里，立着这辆车唯一的货物：一扇独立摆放的木框窗户，木纹清晰可见，玻璃保持透亮，笔直立着而不是平放。一根细绳把一张空白纸质挂牌系在窗框上，上面什么都没写。购物车的网格钢丝、小号脚轮和窗户的窗棂线条都带着干净利落的边缘，柔和均匀的影棚光把它们照得清清楚楚，低饱和的钢灰色衬着暖色松木和挂牌的素白。购物车落地的地方，带着一层柔和的半透明接触阴影，体现在alpha通道里，脚轮处最深、向外淡出，购物车和窗户四周都留有清晰边距，没有任何部分触碰或被画框边缘裁切。
