   异寻 etpal · 官网 v5
   ------------------------------------------------------------
   只借 App UI 的「配色与气质」，不借它的控件语言。
   配色：浅暖绿灰底 / 荧光黄绿强调 / 深林绿主色。
   气质：干净、通透、柔和、有呼吸感。

   与 v4 的区别——v4 把 App 的控件（胶囊按钮、徽章、浮层卡片、
   卡中卡）搬到了网页上；v5 回到网页自己的编辑语言：
     · 分区用「大号数字 + 细线」，不用胶囊徽章
     · 按钮是直角小圆角块，不是药丸
     · 内容直接铺在底色上，用细线分隔，不套白卡
     · 头部是普通吸顶条 + 1px 细线，不是悬浮胶囊
     · 标题强调用荧光绿划痕，不用色块反白
     · 图片大画幅、少圆角、不浮起
