THEN Move the setInterval calls that schedule periodic notifications from the server creation to a separate startNotificationIntervals function. Only invoke that function when a client actually connects to the SSE endpoint, so the server does not attempt to send messages before a transport is established.

// Before: server creation starts timers
const server = new Server(...);
setInterval(() => server.notification(...), 5000);

// After: define startNotificationIntervals and call it in the connect handler
const server = new Server(...);
function startNotificationIntervals(transport) {
  setInterval(() => transport.send(...), 5000);
}
// On client connection: startNotificationIntervals(transport);
