+Enhancement: Consistent initial loading spinner
+
+We have updated the loading spinner on the initial page load to run continuously during the client bootstrap. Previously, the spinner would appear and disappear multiple times.
+
+Additionally, we have aligned the spinner's design with our other loading spinners and reduced the delay before it appears from 1 second to 0.5 seconds.
