// qa/qa_push.js — send a REAL notification+data FCM to a user's token (faithful to the app's own
// pushes) so a KILLED app shows it in the shade and tapping it cold-starts via the real OS splash
// handover. This is the ONE path that reproduces the "opens-and-closes" crash class (e.g. the
// splash-exit iconView NPE) — `adb am start --es …` does NOT (different launch path), and
// `am force-stop` can't even receive FCM. See ClaudeQAPlan.md (Pass E crash-triage / reproduction
// fidelity) and memory/project_notifications.md.
