/* ============================================================
 * candycake_cart · cc-select 自研下拉组件样式
 *
 * 目标：替代 bootstrap-select（.selectpicker）的视觉，统一走糖糕绿设计 token，
 *       支持 option.data-content（图片 / SVG / HTML）透传，无侵入替换。
 *
 * 结构（由 cc-select.js progressive enhance 后生成）：
 *   .cc-select
 *   ├── select.cc-select__native  （原生 <select>，aria-hidden + 视觉隐藏，保留 form 提交语义）
 *   ├── button.cc-select__trigger （点击切换菜单）
 *   │   ├── .cc-select__trigger-content  （含图标 / 文字 / data-content HTML）
 *   │   └── .cc-select__chevron
 *   └── .cc-select__menu (role=listbox)
 *       └── .cc-select__option (role=option)[.is-selected][.is-active][.is-disabled]
 *           └── .cc-select__option-content
