/* =====================================================================
 * [PBCS PATCH] channel-article.html 专用现代样式 — channel-article-modern.css
 * ---------------------------------------------------------------------
 * 背景：channel-article.html 之前是「焦点视点横滑 + 8/4 主列表 + 侧栏 widget」
 *       用 Bootstrap 4 默认 .badge / .btn 风格，视觉陈旧。
 * 改成与 channel-download.html / show-news.html / show-download.html 一致
 * 的现代杂志/科技门户风。
 *
 * 命名空间：.pbcs-al- 前缀（article list 简写）
 * 引用：channel-article.html 自己在 head 之后 <link> 引入
 *
 * 设计同 channel-download-modern.css 平行：
 *   - 复用 home-modern.css 通用组件（.pbcs-home-wrap / .pbcs-section）
 *   - 复用 show-news-modern.css 通用组件（.pbcs-news-banner / .pbcs-news-breadcrumb /
 *     .pbcs-sidebar / .pbcs-widget / .pbcs-tagcloud）
 *   - 本文件新增：headline 横滑 carousel / tabs pill 导航 / list item 卡片 /
 *     rank 排行 / rec 推荐 / Element Plus 风格分页 + 跳转
 * ===================================================================== */
