/* =========================================
 * 首页技术支持区 - 新闻媒体模块样式
 * 应用于 .flex-support-wrap / .flex-news / .news-scroll
 *
 * 视觉规范（参考子菜单"媒体报道"页）：
 *   - 标题在上、日期在下、虚线分隔
 *   - 黑字白底
 *   - 头删+尾加滚动（JS 每 2s 向上滑一行，动画结束后删除首条 li 并追加新 li）
 *
 * v6 关键变更：
 *   - 改为"头删+尾加"轮播：每次 tick 删除首条 li 并追加新 li，永不复制数据
 *   - li 固定高度 84px，保证每行严格对齐
 *   - 容器高度 = 84 × 行数，桌面 5 行 / 移动 4 行
 *
 * v8 关键变更：
 *   - .flex-news 改为 height:auto + min-height:0，完全由 JS 强同步高度，
 *     不再依赖 CSS min-height 下限。JS 使用 ResizeObserver + window.resize(16ms)
 *     实现窗口 resize 时实时同步。
