Legacy server-key API is dead (June 2024) — use HTTP v1 with OAuth service account
POST /v1/projects/{id}/messages:send with message {token, notification, data}
Mint access tokens from the service account (google-auth library handles caching)
Handle UNREGISTERED responses by deleting the stale device token

Known gotchas

Legacy /fcm/send endpoint returns 404 since mid-2024 — migrate to v1
data payload values must all be strings — numbers/booleans get rejected
iOS delivery needs APNs config (key upload) and apns headers for priority; silent pushes are throttled by iOS itself
