/*
 * solutions-hub.css —— 行业方案总页新版 ?new=1 测试页（英文站 /application4332/?new=1，正文由 app\service\SolutionsHub 输出）
 * 按 Claude Design「VOOHU 英文站行业方案总页」逐值还原：桌面 ≥1100、平板 700–1099、手机 <700 三档（设计稿自带的三档）。
 * 相对设计稿：领域 / 接口卡片恢复了一行设备说明（交接包定稿有，设计稿漏了），手机上卡片因此改成单列横排。
 * 全部规则收在 #vh-solhub 下（id 前缀压过站点通用样式），不影响页头页脚。
 * 内容宽度按全站约定（vh-layout.css）：<1440 为 1200 居中（两侧 24），≥1440 跟随内容列 --vh-page；不写 vw（≥2048 有 zoom）。
 * 字体：英文正文用应用领域页同一套自托管 "VHAP Poppins"（application-preview-fonts.css，400 / 600 / 700）。
