   Moreast — 网站开发页专属布局文件（页眉 / 页脚 / 导航）
   ---------------------------------------------------------
   本文件【仅 web-development.html】使用，管理该页的页面框架样式：
     · 顶部导航（.site-header / .nav / .nav__*）
     · 移动端折叠菜单（.nav__toggle / .is-open）
     · 页脚（.site-footer / .footer__*）
   与各页内容样式 styles.css 完全分离。
   对应结构由 web-development-header.js 注入（<div id="site-header"> /
   <div id="site-footer">）。
   注意：本文件依赖 styles.css 中定义的 :root 设计变量。
