   模块：新闻列表页 + 新闻内容详情页
   作用：
   1. 统一二级Banner、双栏主体、栏目标题、右侧原创文章、
      宣传图片及响应式规则；
   2. 保留新闻列表页专用的列表样式；
   3. 保留新闻详情页专用的正文排版与媒体兼容样式；
   4. 右侧宣传图片统一使用新闻列表页的
      .news-sidebar__promotions 与 .news-promo-card；
   5. 删除 news-list.css 与 news-detail.css 中重复定义。
   说明：
   - 新闻列表分页继续由独立的 list-pagination.css 控制；
   - 本文件不定义公共头部、公共底部和分页组件。
