/* ==========================================================================
   EEYUN 统一 FAQ 模板  (static/css/faq.css)
   ---------------------------------------------------------------------------
   版式与 about / blog / seg 改版后的「规格单」语言一致：
   红色小标 + 左对齐大标题 + 细线分隔 + 右侧细 +/−，展开时才出答案。
   仅供参考的旧样式：无编号（两列排布时编号会重复起号）

     <section class="faq-sec">
       <span class="faq-eyebrow">FAQ <em>· 5 questions</em></span>
       <h2 class="faq-h2">Frequently asked questions …</h2>
       <p class="faq-lead">…</p>
       <div class="faq-wrap">
         <div class="faq-item is-open">                 <!-- 首条默认展开 -->
           <div class="faq-question">问题<span class="faq-icon"></span></div>
           <div class="faq-answer"><p>答案</p></div>
         </div>
         …
   点击行为：切换父级 .faq-item 的 is-open（各页内联一行脚本）
