/*
 * 稼享指南：固定的活动报名组件样式。
 * 独立于视频、意见反馈和全站 CSS；只需引入本文件即可复用。
 *
 * 根节点：event-registration
 * 单活动：event-registration--single（绿色日期块 + 活动说明 + 报名入口）
 * 多活动：event-registration--multiple（48px 日期栏 + 一行报名横条）
 * 已结束：event-registration--empty（保留结束提示，不提供报名链接）
 *
 * 每场活动只保留一份 .event-registration__card，日期和说明在单活动
 * 模式显示，多活动模式隐藏。切换和到期检查由 index_renew.js 负责。
 * 可在根节点覆盖 --registration-* 变量；不必修改两套布局。
 * 多活动日期栏默认用于同一月份的一组活动，月份显示在栏目右上角。
