楼梯尽头的窗，给影子留了一个框

Minimal architectural photograph looking upward through a dim lime-plastered stairwell. A narrow rectangular window frames a patch of blue sky; handrail shadows bend into geometric lines along the warm white grainy wall. Natural perspective, no people, hard noon light.

极简建筑摄影，从昏暗石灰墙楼梯间向上看，一扇窄矩形窗套住一小片蓝天，扶手影子沿墙折成几何线。暖白墙面细颗粒可见，透视自然，空无一人，正午硬光。
