/*
 * 新闻中心新版（模板 public/themes/template/news_center/*，设计包「沃虎官网新闻中心设计方案」）。
 * 所有规则限定在 main.nc 之内；颜色 / 字号 / 间距照设计稿 news/NOTES.md 的网格与数学规范：
 * 容器 1200 + 两侧 24；间距 8/16/24/32/48/64/96；字号 12/16 · 13/20 · 14/24 · 15/24 · 16/24 · 18/28 · 26/36 · 32/40 · 48/56；
 * 圆角 10（首屏栏目条 5）；卡片悬停只变红边框（边框画在 ::after 叠层上，不占尺寸）。
 * 中文站 cn-typography.css 给所有元素强制 Noto Sans SC（!important），封面标签的宋体在本文件末尾用更高优先级覆盖。
