just stumbled onto a way to use new BroadcastChannel('name') to keep multiple tabs in sync w/o hitting the server constantly. its pretty seamless for making sure things like cart updates or user sessions stay perfectly aligned across every open window. anyone else using this instead of localStorage session storage for real-time UI updates?

still need a fallback for when users have the site open in a background tab thats been hibernating for hours. broadcast channel is great, but if the page was discarded by the browser, it wont catch the message. i usually pair it w/ a
storage
event listener on localStorage just to be absolutely certain the state catches up on reload.
