/* ============================================================================
   site.css —— 二开样式层（左侧栏布局）
   ----------------------------------------------------------------------------
   原模板样式完整保留在 css/style.css（未做任何修改），本文件在其之上做三件事：
     1. 建立设计令牌，统一深浅色（沿用原模板的 --dark-mode-* 变量机制）
     2. 布局从"居中单卡"改为"固定左栏 + 右侧正文"，断点 768px
     3. 作品 / 博客 / 相册 / 友链 四个板块的组件样式
   侧栏尺寸与密度参考 2x.nz：252px 宽、菜单项 32px 高 / 12.5px 字 / 10px 圆角。
   加载顺序必须在 style.css 之后。
