 当前实现已按这个结构输出；带描述的开关行增加 `has-description` 修饰类，让描述与标签对齐。

+## 8. 本轮细节修正
+
+- 下拉列表不再设置 `scrollbar-gutter`；无溢出时不预留滚动条空间。
+- 选项数 > 6 时 `overflow-y: scroll`，否则 `auto`；选项固定高度 `2.563em`，不参与 flex 收缩。
+- 滑杆百分比 `(xx%)` 使用原版浅绿 `rgb(162,255,106)`。
+- 开关与文字之间增加 `0.75em` 间距。
+- 开关背景提高到 `rgba(118,255,51,0.35)` / `rgba(191,213,255,0.35)`，更接近原版亮度。
+- 侧边栏选中文字改为 `display:flex; align-items:center; height:100%`，垂直居中。
+- `.ms-top` 只保留定位，不再叠加半透明背景；HEAD 背景由 `HeadScreen.RootStyle` 的原版渐变提供。
