       历史：① 更早的「relative + width:100%」把 .main-chat 挤成 0 宽；② 2026-09-11 改成
       全屏覆盖抽屉 —— 不塌了，但全有全无、用户不可调，且整屏盖住聊天与输入行。
       实测（Playwright 360x740，见 tests/_diag_handle_20260912.log）：**左右分屏在本应用行不通**
       —— .input-container 左侧的 .input-toolbar 固定占去约 137px，聊天列窄于 ~326px 时
       #messageInput 只剩 16px 宽、右缘还越界到面板之下，其中心点 elementFromPoint 命中分隔条。
       故改为**上下分屏**：面板固定在底部、高度可控；聊天列宽度恒为 100%（零挤压，直接满足
       「不得重新引入挤压」），输入行位于聊天列底部、恒在分隔条之上 -> 完全可见且 9 点全部命中。
       面板高度由 JS clamp 到 [35%, 70%]（上界由「聊天列 >=30% 视口高且 >=200px」地板反推）。 */
