   · 玻璃：rgba(255,255,255,.1) + blur(20px) + 1px 白色高光边
   · 缓动：cubic-bezier(.33,1,.68,1)，时长 200-300ms
   · 圆角：统一 8px / 10px（不用大圆角）
   · 渐变：conic-gradient 三色低饱和缓慢旋转
   · 图标：全部 SVG（Lucide 路径），禁止 emoji
   · 交互：全部 Lottie，禁止 CSS keyframes

   按钮文字（建议 / 历史 / 昵称）**保持显示**——站长明确要求过：

   代价是 390px 宽度塞不下「品牌 + 建议 + 历史 + 昵称」，所以要主动让位：
     1. 品牌允许收缩（min-width:0 + 省略号），而不是把按钮挤扁；
