   蝉脉 · 功能子页内嵌历史（fhist.css）
   ---------------------------------------------------------------------
   2026-09-21 改版：**历史从"页面里的折叠卡"改成"顶部页签的第二页"**
     用户指令：「所有的生成历史都应该以红框里的生成历史为标准，去掉蓝框的生成历史卡，
               全站每个功能的生成历史，全按照绘画MAX红格子里这种生成历史的方式去改」
     即：每个功能子页顶部给一排**页签**（<功能名> / 生成历史），点「生成历史」就是
     整页的历史列表 —— 视觉与「绘画MAX」的生成历史页一致。
     原型：public/paintmax.css 的 .pm-tabs / .pm-hist-*（本文件按它逐条对齐数值）。

   独立文件：不覆盖任何既有样式，全部类名以 .cmfhist / .cmfh 前缀隔离。
   配色取自 style.css 的 :root（品牌橙 --primary: #f95901），不换品牌色。

/* ---------- 两个"页"的切换：不动 DOM，只用 CSS 显隐 ----------
   🔴 这里刻意用「链式 :not()」而不是给兄弟节点打标记：
      功能页的内容是别人写的、可能**在打开后还会动态追加**节点，
      打标记只能在切换那一刻打一次，后追加的就漏了；
      链式 :not() 由 CSS 每次重算，后加的子节点自动一起被藏起来。
      （:not(a):not(b) 这种简单选择器链在全部现代浏览器都支持） */
