// Command vapidgen prints a new VAPID key pair for Web Push. The public key
// line goes into deploy/.env as is; the private key line goes, alone, into
// the secret file MEALQUEST_VAPID_PRIVATE_KEY_FILE names. Both keys are
// unpadded base64url P-256 keys, the encoding config.Load validates.
//
// go run ./cmd/vapidgen
