// Live-sandbox verification run (not part of the regular regression suite).
//
// Unlike e2e/electron-smoke.spec.ts (which deliberately uses a fake
// JMAP_SERVER_URL just to skip the /setup wizard, and never expects a real
// server on the other end), this spec launches the exact same packaged
// artifact against the REAL sandbox JMAP backend at
// https://stalwart.sandbox.vnc.de and proves:
//   1. the login screen renders with no TLS/network errors reaching that host
//   2. submitting an obviously-fake, nonexistent test credential produces a
//      structured "invalid credentials" style response from the real server
//      (not a network failure) - proving the renderer -> Next API route ->
//      real JMAP server round trip works end-to-end, without ever using or
//      guessing a real account's credentials.
