月亮升起时，天文台只亮一扇门

One wide 3:2 landscape painting of a small white desert observatory at moonrise. The domed building sits low on a terracotta ridge, one warm doorway gives scale, pale lavender sky and a modest near-full moon well above the roof. Restrained gouache and colored-pencil texture on sand-toned paper, broad quiet shapes, no stars crowding the sky and no people. No text or watermark.

3:2宽幅风景画：月升时的小白色沙漠天文台。圆顶建筑低置于陶红山脊，一扇暖门光提示尺度，淡薰衣草天空，适度大小的近满月高于屋顶。沙色纸上克制的水粉与彩铅质感，大块安静形状，天空不堆星，没有人物、文字或水印。
