   v5 皮肤 — 按用户给的参考稿（_originals/ref/style-ref.png）重做外观
   叠在 style.css 之上，只改「长相」，不动结构脚本。

   参考稿的视觉语言：
   - 大片照片打底的深色首屏，透明顶栏，导航居中，选中项下面一道白线
   - 白底 / 浅灰底交替的内容区，标题不夸张（40px 上下），正文灰
   - 深海军蓝的工厂区：左文案，右边一张斜切的车间照；下面一条线性图标数据条
   - 按钮方角：深底上是白实底 + 白描边，浅底上是海军蓝实底
   - 眉标是宽字距的大写小字，不再用等宽字体和方块前缀
   毛玻璃保留：顶栏（滚动后）、数据条、首屏/收尾区的描边按钮、播放钮、照片上的角标
