/* 公开店铺优惠券标签 + 领取弹窗（FEAT-PUBLIC-PRODUCT-COUPON-BADGE-01）
 *
 * 全局共享样式，供 dealer-web / factory-web 公开店铺的首页/商品列表/详情页复用。
 * 原则：
 *   1. 标签紧贴价格右侧、尺寸包裹内容，不得占满价格行/遮挡价格标题图片。
 *   2. 弹窗在移动端为底部抽屉、桌面端居中卡片，320/375/390/桌面端均不产生横向溢出。
 *   3. 全部为后端返回字段驱动；前端仅在 couponAvailable 为真时出现标签。
 */

/* ---------- 价格后标签 ---------- */
/* 仅当价格元素内被挂载券标签时加入修饰类，使价格+标签同行且可自动换行，避免溢出。
   文本节点在 flex 容器内视为匿名 flex item，标签自然排到价格右侧。 */
