  // We deliberately do NOT pass it as an explicit `baseUrl` to the SDK: doing
  // so collapses `resolveApiUrls` to a single-element URL list, which short-
  // circuits `_withFallback` (`apiUrls.length <= 1` branch). The SDK reads the
  // same env var internally and additionally appends its hardcoded fallback
  // URLs, which is what the e2e-fallback-tests workflow relies on so backend
  // self-calls (quota debits in email-queue-step, send-test-email, analytics
  // events batch, etc.) survive a primary-port outage.
