/* ============================================================
   17. 布局修复（2026-09-22）：输入框钉底 · 只有消息区滚动 · 图片不撑破布局
   根因：
     ① `.app{min-height:100vh}` + `.inbox{height:calc(100dvh - 60px)}` + 页面内边距
        → 总高超出视口，body 产生滚动，底部输入区被推到屏幕外（工作台实测 bottom 924 > 900）。
     ② `.app,.auth-wrap,.guest{min-height:100vh}` 在手机上 100vh > 可视高度，
        `.guest` 被撑高 → 整页可滚、输入框跟随滚动。
     ③ 访客聊天图片只有 max-width 没有 max-height，720×2400 长图渲染成 733px 高，
        一张图占满整个视口，滚动观感就是「输入框在跑」。
   方案：外层锁定为视口高度并禁止页面滚动，滚动只发生在消息容器内；
        图片钳制高度 + 固定占位背景，加载/尺寸变化都不推动布局。

   20. 移动端软键盘定版（2026-09-22）：只压缩聊天滚动区，输入框贴键盘上沿
   背景：iOS Safari 弹键盘时不会重排 fixed 元素，浏览器会把整个页面向上顶
        （visualViewport.offsetTop 变化），于是「输入框跑到屏幕顶部」。
   方案：
     · 聊天页外壳 body 固定（position:fixed + overflow:hidden）→ 页面本身不可能滚动
     · 用 visualViewport 的真实 height/offsetTop 驱动三个 CSS 变量：
         --vvh 可视高度  --vvy 可视区顶偏移  --kb-h 键盘占去的高度
     · 键盘打开时：外壳 top 跟随 --vvy、高度 = --vvh；输入框 bottom = --kb-h
       → 输入框永远紧贴键盘上沿，页面不产生任何位移
