   面板是完整界面, 缩到很小时内容会糊成一团 —— 所以节奏必须这样配, 让糊的那几帧根本来不及被看见:
   1) 起步极快: 曲线 y1 > 1(x1 很小), 0.02 → 0.6 只花前 12% 的时间, 糊的帧只有两三帧;
   2) 淡入压在更短的前 12% 里完成, 最难看的一段正好被透明度盖住;
   3) 末端 y1=1.3 带来约 3% 的过冲再落回 —— "弹一下"的手感, 不至于像玩具。
   退场反过来: 起步快、一路收那一点, 后 62% 边收边淡出(半透明的糊比实心的糊不显眼)。
   时长入场 .36s / 退场 .28s: 用户要"再慢一点、更跟手", 而且 60Hz 屏上时长越短分摊到的帧越少(显得跳),
   放慢后同样的位移铺在更多帧上, 观感更顺。想更快就同步缩短, 但别低于 .2s。

   ------------------------------------------------------------
   设计原则:
     1) 桌面端观感一个像素都不动 —— 全部改动都关在媒体查询里;
     2) ≤820px: 侧边栏变成"抽屉"(汉堡按钮 + 遮罩), 顶栏收紧;
     3) ≤700px: 弹窗/聊天窗/小邮面板改成"底部卡片(近全屏)", 表单单列,
        输入框字号 ≥16px(否则 iOS Safari 会自动放大页面);
     4) 触摸屏(pointer: coarse): 加大可点区域, 去掉只能用鼠标的交互
        (拖动缩放窗口等, 见 app.js 的移动端分支)。
   断点说明: 820 用于"横向宽度不够放侧边栏+内容"的平板竖屏;
             700 用于手机(横向真的放不下两列表单/居中小窗)。
