/*
 * 其它公告页面样式
 * ------------------------------------------------------------------
 * 风格基准：投资者关系页「公告（沪市）」——蓝(#2F79ED)白配色、
 *          component-title 标题区、about-us-navigation 顶部 tab 行。
 * 列表皮肤：.skin-notice（仿公告，默认） / .skin-news（参考新闻）
 *          / .skin-blog（参考技术博客），由页面配置切换，DOM 结构不变。
 * 命名空间统一用 on- 前缀，避免与站内 main.css / news.css 冲突。
