	// Seq is a monotonic, bus-global sequence number stamped on every published
	// event. Delivery to a slow subscriber is still lossy by design (a full
	// buffer drops rather than blocking the hot path), but the seq makes drops
	// DETECTABLE: a client that sees the sequence jump knows it missed events and
	// can resync. Control frames sent directly by the SSE handler
	// (server.connected/config/heartbeat) do not go through Publish and carry no
	// seq (0), so clients must ignore seq 0 for gap detection.
