/**
 * 视口适配模式（2026-10-27 v2）— 首页「一屏完整呈现 · 无滚动条」
 * 触发：body.vf-home（仅首页默认视图；搜索/排序/分页/板块视图自动退出）
 *
 * 手段（v2 实测调优）：
 *   1. .au-stage 锁 100dvh 弹性列：hero/主体/页脚三段，主体 min-height:0 防溢出
 *   2. Hero 68vh → 17vh；客服公示/公告隐藏；数据带单行薄片
 *   3. 板块广场卡片定高 118px（关 aspect-ratio 拉伸），首屏一行 6 张
 *   4. 修复 flex 换行：row.g-4 改 nowrap + 弹性列宽（此前 col 66%+33%+gap 溢出换行，
 *      row 被撑到 945px —— 滚动条元凶之一）
 *   5. 帖子卡紧凑化（标题+元信息一行），侧栏保留欢迎卡+推荐前3
 *   6. FAQ 折叠 + [open] 悬浮层展开（不撑高文档）
 *   7. 页脚压成单行
 *   8. ≥880px 高的桌面端才启用；矮屏自动回退常规滚动（保证可用性）
