/* ============================================================
 * 2026-10-05 修复：新回复气泡被操作组挤成「逐字竖排」
 * ------------------------------------------------------------
 * 根因（无头浏览器实测复现，conv 6298 现场抓取）：
 *   .ss-row 是 nowrap 水平 flex。长回复（>200 字）触发 doc 视图后，
 *   ai-ux.js 会把 ss-doc-avatar(27px) + ss-doc-actions(119px) 注入，
 *   另有 ss-ts(36px) + ss-ux-ops(67px) + ss-fb(95px) 反馈组，
 *   全部水平排在同一行 —— 固定占用 ≈ 344px + 5 个 gap，
 *   行宽只有 ~410px，气泡被压到 25px 宽。
 *   CJK 文本的 min-content = 1 个字宽 → 一个字一行「竖排」。
 *   历史消息不注入这些元素，所以只有每条新回复中招（GIF 里尤其明显）。
 * 修法（CSS only，不动 JS/DOM）：
 *   1) row 允许换行；操作栏/快捷操作/反馈组独占一行 ——
 *      ss-doc-actions 原样式（margin-top+border-top）本来就是
 *      「气泡下方底栏」的设计意图，水平排属于布局断裂。
 *   2) 悬停浮现类元素在未激活时不参与布局（display:none），
 *      避免每条消息下方常驻大片空白；放弃 opacity 过渡（微信/ChatGPT 同款直出）。
 *   3) 气泡设保底 min-width，任何情况下不会再窄于 12em。
 *   4) 触屏（≤640px）与 prefers-reduced-motion 原本就常显的元素，
 *      在对应场景恢复 display:flex，不丢可达性。
 * ============================================================ */
