/* ===== 导航栏响应式：按钮到 5 个之后，1240px 以下改用流式布局 =====
   宽屏是三段 absolute 布局（logo 左 / nav 居中 / 用户区右），而 .navbar-nav 的宽度
   等于**内容宽度、不会自己收缩** —— 内容一变宽就直接压到右侧用户区上，且不报错。
   2026-09-28 加第 5 个按钮「同步练习」后，1024 视口实测压掉 7px
   （更早四枚按钮时 1024 也只剩 12px 余量，本来就贴着）。
   1240 以下改成常规流式：nav 占据 logo 与用户区之间的弹性空间，装不下才横滚。
   ★ 首尾子项 margin:auto 是关键写法：空间够时视觉仍然居中（与宽屏观感一致），
     空间不够时自动贴左并可横滚 —— 若直接写 justify-content:center，
     溢出后左边的按钮会被裁掉且滚不回去（经典坑）。

       ② 再从半径 84% 处径向羽化 → 图案外缘不做硬切，直接化开。
