   泰华液压 · Taihua Equipment —— 模板样式（CMS 零样式：模板自带全部样式）
   ------------------------------------------------------------
   架构：CMS 不带任何样式；本文件 + widgets 骨架 HTML + scripts/main.js
        就是最终视觉与交互，CMS 只负责提供字段数据。

   来源：严格对照已确认的原型 prototype/styles.css（2026-09-17 用户评审通过）
        · 设计令牌（--tp-*）原样保留
        · 新增：极简 reset 取代 Tailwind preflight（避免 h1 字重/字号被重置，
          原型依赖浏览器默认标题样式，而 preflight 会把标题变成 inherit）
        · 新增：骨架需要的类（轮播分层、导航下拉/移动菜单、图库、Tab、弹窗、
          里程碑表、询盘两栏）——按原型同类语言续写

   结构约定：模板驱动模式下 CMS 会展平容器，所以「一个骨架 = 一个完整版块」，
             版块背景/内边距/标题行全部在本文件 + 骨架里表达。
   ============================================================ */

   为什么不用 fonts.googleapis.com：本站 CSP 的 style-src 白名单只放了 cdn.jsdelivr.net，
   Google 那支 CSS 会被直接拦掉（实测全站 Poppins/Inter 从未加载，一直在吃后备字体）。
   Fontsource 的字体文件是相对路径 ./files/xxx.woff2，解析后仍落在 cdn.jsdelivr.net 上，
   style-src 与 font-src 两个白名单都放行。

   框架 render-widget.tsx 按 colSticky 给列加 .widget-flex-row__cell--sticky，

   ⚠ 公共侧是「零 CMS 样式」：styles/base/widgets.css 只被后台布局引入，
   所以这条规则【必须由模板包提供】。缺了它 → 勾了「逐列吸顶」毫无反应，
   而后台编辑器里看着却是好的（那边加载了 widgets.css），极易误判成操作错误。
