/* 英文站首页第五轮（2026-10，Claude Design 设计稿）。只作用于 .v5 板块和首页页脚证书标签；模板 common/home_en_v5.html。
 * 站上 .vhd-home h1/h2/p 等规则会清零外边距，这里的规则都带 .v5 前缀（两个类名）以免被压掉。 */
/* 第五轮：Claude Design「VOOHU 英文站首页.dc.html」（2026-10-14）落地样式
 * 断点：< 700 手机（基础样式）；700–1099 平板；≥ 1100 桌面。列数按断点固定，不用 auto-fill。
 * 全部规则挂在 .v5 下：站上首页有 .vhd-home h1/h2/h3/p/ol { margin: 0 } 等重置，单类选择器压不过。
 * 进模板时作为独立 .css 引入（CLAUDE.md Footgun 5：模板里不写内联 <style>/<script> 的 {}）。 */
