u"""南侧板 v4 —— 跟着 15 mm 分风腔加长（2026-09-13）。

与 v3 的差别只有两处，都是「端板外移 11」的下游：
  · 长度 x −27.4~125.4（152.8）⇒ **−38.4~136.4（175.0）**
  · A 组螺丝孔 x −13.70/111.70 ⇒ **−31/129**（端板角柱中心），z 2.0/60.0 ⇒ **10/60**
    ⛔ 旧的 x=−13.70 打在端板的**空气**里：端板在 z=72 那层只有 2.4 厚的板本体，
       L 脚在底部 z 0~2.4，中间是空的。v10 加的角柱（x −36~−26 / 124~134，截面 8×10、
       通高 z 0~72）才是这 8 颗螺丝真正能拧进去的肉。
  · B 组 3 个孔（x 30/49/68, z −5）保留 —— B 组已取消，孔留着无害（PROGRESS 已记）。

其余（USB-C 开口位置 13×9、板厚、z 范围）与 v3 逐字相同：开口对准的是底板上的座子，
座子没动 ⇒ 开口不能动。

⛔ 竖板、法线沿 y ⇒ 画在**上视基准面**：草图 (u,v) → 模型 (x, −z)，拉伸法线 +y。
⛔ 画草图前必须 `sm.AddToDB = True`。
⛔ 判据：矩形开口用不了圆柱面计数 ⇒ 用面数（6 + 每个通口 4）+ Ø3.4 圆柱面计数。
