// based on https://gist.github.com/thomas-lowry/4d2d890ae5dfd4ab4eccebc4da99d52d with added return safety
const getPage = (node) => {
  let item = node;
  while (item && item.type !== "PAGE") {
    item = item.parent;
  }
  // Return item if it's a PAGE node, otherwise return an empty string
  return item?.type === "PAGE" ? item : "";
};

// pages without a parent are in a different document.
