It's not clear from searching on Google and looking through documentation. What's the maximum length on a message sent via Window.postMessage (https://developer.mozilla.org/en-US/docs/Web/API/Window.postMessage)? We assume this varies by browser?

As a data point, the WebKit implementation (used by Safari and Chrome)
doesn't currently enforce any limits (other than those imposed by running
out of memory).
