/**
|
||
* 微信订阅消息**模板登记表**的单元测试（`npm test` 跑）。
|
||
*
|
||
* 为什么值得测：模板 ID 或字段名写错，线上表现只有一句 `47003 argument invalid`，
|
||
* 整条通知发不出去且看不出哪里错。这里把「认哪些模板、字段怎么映射、环境变量覆盖
|
||
* 怎么合并」全部钉死，改坏了在 CI 就红。
|
||
*
|
||
* 可以直接 `import` 这个 .ts 文件，是因为 Node 22+ 会剥离类型标注；本文件刻意不依赖
|
||
* Nuxt 别名（`~~/server/...`），所以纯 `node --test` 就能跑。
