This transform is pretty simple and just modifies the root node's class list:
bridge.registerListener( "setPageProtected", function( payload ) {
var el = document.getElementsByTagName( "html" )[0];
if (!el.classList.contains("page-protected") && payload.protect) {
el.classList.add("page-protected");
}
else if (el.classList.contains("page-protected") && !payload.protect) {
el.classList.remove("page-protected");
}
if (!el.classList.contains("no-editing") && payload.noedit) {
el.classList.add("no-editing");
}
else if (el.classList.contains("no-editing") && !payload.noedit) {
el.classList.remove("no-editing");
}
} );
