/* ============================================================
   wpdx-liezhe 子主题 — 分类页专属样式 (category.css)
   ------------------------------------------------------------
   作用域：.lz-category
   设计稿来源：HTML/02-07 各级分类页 <style> 块
   依赖：
     - style.css   提供 CSS 变量
     - components.css 提供
       .panel / .section / .sec-head / .hub-hero / .hstats
       .cs-type1 ~ .cs-type4 / .col-list / .post / .side-panel
       .cluster / .sub-layout / .more-btn / .vip-panel / .pop / .tagcloud
   仅在此文件中实现：
     - 同级互链 .sib-list / .sib-back
     - 暂无内容提示 .no-posts
     - 分类页专属组件（mid-cta / decision-grid / case-feed / faq / bot-cta / relhub）
     - 子分类锚点导航 .cluster-nav
     - 响应式补丁
