/**
 * 名片 DIY 组件 · 名片级自定义二维码(card.qr_image)契约测试
 *
 * 背景(2.20):
 *   此前二维码只有两个来源 —— 组件级自定义图(c.qrImage)与系统生成码(card.qr_url)。
 *   2.20 起每张名片(员工名片/企业名片)可各自持有一张自定义二维码图片,
 *   DIY 组件按三层优先级取用:
 *     1) 名片级  card.qr_image  ← 每张名片各自一张(「我的名片」登录后即见本人那张)
 *     2) 组件级  c.qrImage       ← 装修期统一指定(名片自己没设图时生效)
 *     3) 系统码  card.qr_url     ← 兜底(原有行为)
 *
 * 覆盖:
 *   1. mini 基件 qrSrc 按上述优先级取值(源码契约 + 真实求值双证)
 *   2. 组件级 qrImage 仍完整保留(未被名片级顶掉)
 *   3. 反例: 虚构字段不得出现(防恒真)
 *
 * 跑法: node --test tests/diy-card-qr-image-source.test.js
