+/**
+ * 名片 DIY 组件 · 路径A(组件卡 → 跳完整名片页)链路测试
+ *
+ * 背景:
+ *   商家端装修页嵌入名片组件后, C 端(微页面/小程序)渲染的是组件内迷你卡。
+ *   参考图形态(名片卡 + 二维码 + 全宽「发名片」)的完整功能不在组件里, 而在
+ *   现成的会员端详情页 /pages_tool/card/detail —— 组件靠「查看完整名片」
+ *   全宽主按钮把用户送过去(路径A)。游客未登录时 detail.vue 自动
+ *   fallbackToPublicPage 落地 wap 公开页(保存通讯录/分享/二维码), 不是死路。
+ *
+ * 本测试把这条链路的源码契约固化为断言, 防回归:
+ *   1. show/self 两个单卡组件的 miniConfig 透传 showDetailBtn + detailBtnText
+ *   2. 两个组件模板都挂 @detail="goDetail"(基件 emit('detail') 有接收方)
+ *   3. goDetail 跳 /pages_tool/card/detail 且带 card_id 参数
+ *   4. mini 基件: showDetailBtn flagOn 默认开(开箱即用) + 全宽按钮 emit detail
+ *   5. detail.vue 游客兜底: 错误信封带 wap_url → fallbackToPublicPage(死路防护)
+ *
+ * 口径: 断言前先剔除注释(HTML/块/行注释), 防止「注释里写了某写法」被算实现
+ *      (本项目踩过: 注释里写「绝不能写 X」把自己判违规)。
+ * 反例: 虚构选择器/不存在的字段必须查不到, 证明断言不是恒真。
+ *
+ * 跑法: node --test tests/diy-card-detail-jump.test.js
