/* ============================================================
 * candycake_cart · coupon-picker (内嵌列表版)
 *
 * 单张代金券卡片改为"横向票券"样式，与用户中心 /coupons
 * (themes/clientarea/candycake_user/assets/css/coupon.css) 保持视觉一致：
 *   - 左侧 40px 竖排"代金券"标签 + 虚线分割
 *   - 上下半圆缺口（::before / ::after）
 *   - 三行结构：金额 + 条件 / 信息标签行 / 有效期 + 提示
 *   - 未使用（可用）态走橙黄主题
 *
 * 在用户中心样式之上叠加 cart 专属语义：
 *   - .is-selected   已选中（cart 品牌绿，使用 --cc-brand* token）
 *   - .is-disabled   不可用（沿用 user-center 灰白未使用态）
 *   - .cc-coupon-pick / .cc-coupon-preview 选择提示与"本单可减"
 *
 * 前缀统一 cc-coupon- 避免污染全局。
