YK Playground

A local stand-in for the third-party SaaS our apps depend on. Instead of a real provider, an app redirects (or calls) here; the playground plays back a provider-shaped response and bounces back. No real accounts, money, or sends.

  Text messages + verification codes — logged, never sent.
