/* 下拉框：自绘（button + 浮层），不用原生 select
 *
 * 为什么不用原生 <select>：
 *  1. 原生弹出层由浏览器绘制，Windows Chrome 会忽略 option 的 background，
 *     深色主题下展开是刺眼白底 + 深色字，几乎不可读；
 *  2. 两个 select 内容长度不同（「最近更新」vs「24」），若箭头挂在含 label 的
 *     容器上定位，箭头会与框右缘错开 40px，视觉不统一。
 * 自绘后两者共用同一套变量，天然一致，且完全跟随主题。
 *
 * 结构：.dd > button.dd-btn + .dd-menu > button.dd-opt
 * 原生 select 保留在 DOM 中（隐藏、仍参与表单与 readUrl），由 JS 同步值。 */
