   牛匠直装 官网 · 样式表
   --------------------------------------------------------------------------
   设计口径：
     · 主色 #FFD250（与匠猫 ijiangmao.cn 同一支黄，也是小程序落地主题色）；
     · 黄色的明度很高，**字一定要压在深色上**：主色底配 #151515 字，
       白底上的黄色只能当「标记 / 色块」，正文强调用 --gold（#8A6400），
       否则白底黄字直接看不见；
     · 风格：简洁、直接、明了。一屏只讲一件事，不加无意义的装饰动画；
     · 断点：1180 / 900 / 720 / 480。900 以下整套改成单列 + 底部固定行动条。

   文件顺序：变量 → 基础元件 → 页头/抽屉 → 首页各区 → 子页 → 页脚 → 响应式
