/* 手机端聊天室：独占全屏，并跟随「可视视口」以适配虚拟键盘
 *
 * 原来的问题有两个：
 *   1) 顶栏 52px 与底栏 54px 都是 position:fixed，而 #view-room 在手机上 padding 归零，
 *      于是输入框正好被底栏盖住 —— 表现为「输入框完全看不到」
 *   2) 100dvh 在键盘弹出时各浏览器行为不一致（iOS Safari 压根不改变布局视口），
 *      于是输入框位置乱跳 —— 表现为「位置极其不固定」
 *
 * 解决：进入聊天室时隐藏顶/底栏（room-head 自带返回按钮，不影响导航），
 * 容器改为 position:fixed，高度与顶部偏移取自 JS 写入的 --vv-h / --vv-top
 *（来自 visualViewport，键盘弹出时它才是真正可见的区域，iOS 上也准确）。
