/* ============================================================
   news-v2.css — 「资讯」栏目页 v2（2026-10-19 重构：封面卡片栅格 + 分类筛选）
   ------------------------------------------------------------
   设计基准：**站内既有语汇**，不另立体系
   · 刊头 = px-plinth 渐变语言 + 右侧「归档牌」（媒体卡的另一种用法）
   · 卡片 = 首页 .news-card 语汇的放大版（同边框/同阴影/同 mono 日期/同 2 行截断）
   · 筛选 chip = 站内胶囊语言（与 .button 同半径）
   · 差异性格来自「封面墙 + 时效计量」，不来自新颜色/新形状
   作用域：body.news-page（仅 news.html 引用）
