  /* 抽屉滚动兜底（2026-09-01 补）。坏在哪：抽屉是 position:fixed、高度由内容撑，
     以前既没有 max-height 也没有 overflow —— 内容一超过视口，超出去的那截就永远够不到
     （fixed 元素不跟页面滚，实测 scrollTo 之后最后一项仍在视口外）。
     上一轮给顶栏加「FDE 服务」后 360×640 就实测撞线了：/about 抽屉 608px 高、top 78，
     最后一项「关于我们」落在 621–673，视口只有 640，命中测试直接测不到；
     /index 抽屉 620px、top 68（页面级 <style> 把 top 改成 var(--nav)），末项 613–665 同样被截。
     90px = 78（本表里抽屉的 top）+ 12（底部留白）。**故意按 78 这个最大的 top 算**：
     六个页面级 <style> 把 top 覆盖成 var(--nav)=68px，按 78 算出来的高度对它们只会更保守，
     绝不会算超；反过来按 68 算，about/products 这两页（没有页面级覆盖）就会溢出 10px。
     dvh 那行给移动端浏览器地址栏收放用；不认 dvh 的浏览器丢掉该声明、回落到上一行的 vh。
     overscroll-behavior:contain —— 抽屉滚到头时不把滚动链传给背后的页面。 */

   /fde 专用 —— FDE 服务页（V4 版式）　　新增于 V4 本轮，其余 9 页一行未动
   ──────────────────────────────────────────────────────────────────────────────
   来源：reference/v4/pages/fde.html 的两段内联 <style>。已做四件事，不是照抄：
     1. 差集：只保留 /fde 真正用得到的规则。demo 那两段是四个页面共用的，
        .industry-* / .capability-* / .faq-* / .about-* / .team-* / 表单等全部不在本页；
        页头页尾也不要 —— 本页用的是现网 V22 的 .topbar / .footer，不是 demo 的
        .site-header / .site-footer，所以 demo 的导航、大菜单、移动面板、
        .consult-modal 弹窗、.wecom-sidebar（现网由 wecom-contact.js 自带样式）全部丢弃。
     2. 作用域：全部收在 #main 下。全站只有一份 site.css，demo 的 --color-* 与现网
        V11 深色底盘是两套体系，写进 :root 会当场改掉另外 9 个页面。
        本页需要 demo 版式的内容全在 <main id="main"> 里，唯一例外 .skip-link 单写在全局
        （现网 CSS 里没有这个类，不会撞车）。这样不需要 HTML 配合加任何 class。
     3. 修掉 demo 的已知缺陷：永假哨兵、width:max-content 右溢出、rem 断点、
        背景图拿不到懒加载、transform 平移越界 —— 每处在原地留了「为什么」。
     4. 断点按 DESIGN-SYSTEM §2.5.3 的五档全部改 px；
        640px（企微侧栏）与 1100px（导航折叠）是刻意保留的组件级例外，本页两者都用不到。

   /fde 需要 demo 版式的内容全部在 <main id="main"> 里（唯一例外 .skip-link 单独写在全局），
   自定义属性照常向下继承，所以 #main 就是这一页的边界，且不需要 HTML 配合加任何 class。
   background 取黑：main 顶部有 calc(var(--nav)+8px) 的让位内边距，那条带子要和它下面的
   .page-hero（黑底）连成一片，否则会露出现网 body 的深蓝径向渐变，出现一道色差。
   overflow-x:clip 刻意不继承 —— demo 正是靠它把标题右溢出无声吞掉（信条 3：静默失败最贵）。 */

/* 需求 §7：这句在 ≥1200px 必须单行且不溢出；<1200px 自然换行、不得为单行缩到不可读。
   demo 的做法是第二个 <style> 块里一条 min-width:75rem 的 !important nowrap 文案补丁
   （DESIGN-SYSTEM 记作缺陷 BP-B）——字号和容器宽没有任何关系，是碰巧够宽。
   这里换成构造性保证，三件事写在代码里而不是注释里：
     · min(92vw,1440px) —— .container 在 vw≥1200 时的内容宽。容器公式是
       min(100% - clamp(40px,8vw,160px), 1440px)：vw∈[1200,2000] 时边距恒等于 8vw
       故内容宽 = 0.92vw；vw>2000 时边距锁 160px 但 1440 封顶已经生效。两段都等于该式。
     · ÷15 —— 这句话的排版宽上界。13 个全角字各恒 1em（CJK 字体的定义），
       "15AI" 四个西文各 ≤0.65em，字距 17×(-0.045em)；五种字体栈实测最大 14.3995em，
       取 15em 留 4.2% 余量。
     · 外层再套一次 min()：日后有人调大 clamp，字号也翻不出容器。
   断点用 1200px 整数，与 §2.5.3 的 L 档下沿严格对齐（demo 的 75rem 会随根字号漂移）。 */

/* 缺陷：demo 给这个标题上了 width:max-content 却漏了 max-width（同文件另一处就有正确写法）。
   max-content 会架空 max-width，居中的 margin-inline:auto 在超宽时失效，标题整块从右边溢出，
   再被 html 的 overflow-x 吞掉 —— 不出滚动条，字直接看不见。
   之所以要 max-content：::before 叠了一层同字形的「莱文FDE」渐变文字做描边，
   伪元素 left:0 只有在本体不换行时才和正文对得齐，一换行就错位重影。
   所以按能力分档，而不是简单补一个 max-width：
     <1200px：普通居中块，描边关掉。宁可少一层装饰，也不能让标题看不见。
     ≥1200px：才启用 max-content + 描边。此档已证明放得下 ——
