// Debug/QA: point GitLive Firebase at the local emulators. The iOS simulator shares the host
// network, so 127.0.0.1 reaches the emulators directly. Requires FirebaseApp.configure() to
// have run first (done in iOSApp.swift AppDelegate).
//
// TWO DEFECTS LIVED HERE, and the comment above described neither.
//
// There was NO BUILD GATE. Android has `if (!BuildConfig.USE_FIREBASE_EMULATORS) return`;
// Kotlin/Native has no BuildConfig and nothing took its place, so `initKoin()` — called from
// iOSApp.swift's AppDelegate on EVERY launch — pointed Firebase at 127.0.0.1 in release builds
// too. A shipped iOS app whose Firebase calls all go to a loopback address that is not there.
//
// And the redirect was wrapped in `runCatching { }` with the Result discarded, so neither that
// nor any other failure was ever visible.
