// Stub for openid-client v6+（纯 ESM，含 `import * as oauth from 'oauth4webapi'`）。
// ts-jest 默认走 CJS 解析 → 加载真模块直接 `SyntaxError: Cannot use import statement outside a module`，
// 任何间接 import `app.module` 的 integration test 都会炸（全 15 模块 fail）。
//
// 方案：jest config 走 moduleNameMapper `^openid-client$` → 本 stub，让 require 顺利通过。
// SsoOidcClientService 在 integration test 里被 overrideProvider 替换，本 stub 内容不会被真调；
// production / dev 启动仍走真模块。
//
// 同模式：testing/backend/helpers/otplib-stub.ts。
