   会变一秒默认纯尖角的方形」），但那样入场只剩原地淡入 —— 甲方 2028-09-17 明确要求

     · 动画只在 `.msg-new` 上，而 `.msg-new` 只给**真正刚收到的那一条**（见 chat-render.js 的一次性标记）；
       翻历史/整面重排/上拉加载进来的消息一律 no-animate，永远不会播这个动画；
     · 位移作用在整行（含头像与间隙），气泡圆角本身不参与几何变换的那一帧绘制。

   ★ 甲方口径：不要那个实心色块——「文字加载转圈（不含框的那种）」，占 1~2 行气泡的位置，
     跟正常往下翻消息一样有拉力、能回弹，新消息出来就替换掉这块位置。
   ★ 它是 .chat-view 的 flex 兄弟节点（.chat-header 与 #chat-container 之间），**不在滚动容器里**：
     高度一伸一缩只让消息区盒子变矮/变高，消息内容不重排 → 有真拉力，且不会重演 2026-08 那次
     「流内元素高度动画 → 容器整层重栅格 → 所有气泡闪没一秒」（见 KSTAR-案例库）。
   ★ 无框：没有背景、没有边线、没有阴影、没有毛玻璃（毛玻璃还是合成层重栅格触发器）。
   ★ 高度由 JS 逐帧写（跟手，无过渡）；只有回弹/收尾那一下才走 transition。 */
