// A phone with no push service — GrapheneOS, or any de-Googled Android —
// can't be woken while the app is closed, because Chromium routes web push
// through Firebase. The browser reports that as "Registration failed - push
// service error", which tells nobody anything. The app has to say what's
// actually wrong and what works instead.
