/* ===== WORKBUDDYAI_UPDATE_B [SITE] [2026-10-23 主题站点样式 - Default] =====
   说明：
     1. 这套样式只服务 pages_template 下的站点页面（首页 / 栏目列表 / 关于我们）。
        CMS 内容详情页用的是另一套 cms-front.css，两者互不干扰。
     2. 换肤只改 :root 里的变量，不要改下面的规则 —— 主题目录复制走后
        改 8 个变量就能换出一个新主题。
     3. 断点：1024（平板横） / 820（平板竖） / 560（手机）。 */
