/* *******************************
 * When the user (re)loads the page, React state is lost.
 * However, within the iframe, the Google Apps Script can determine the user account (#0),
 * and communicate its email address to the parent window.
 * In order for this communication to occur, the iframe needs to be rendered alongside the login screen.
 *
 * When the user is already logged into one (or more) Google account(s),
 * React receives the user's email address from the iframe and adds it to its state.
 * This triggers a fresh render, which removes the login screen.
 *
 * When the user is not logged into any Google account, the login screen is rendered.
 * For the reasons just explained, the iframe must also be added to the DOM.
 * Currently:
 *  - Google redirects the page inside the iframe to a login page
 *  - the server response for this login page prevents its rendering within an iframe
 *  - the iframe appears empty
 * However:
 *  - should Google ever fix this error and the iframe properly display a login prompt:
 *     - on the one hand, this page could be dramatically simplified since Google website sign-in would no-longer be necessary
 *     - on the other hand, this page would look horrible until I got around to making changes
 *  - to prevent the latter,
 *    the following CSS rule is intended to hide the iframe in the DOM when the login screen is visible
 *     - a communication channel will still exist
 *     - any content within the iframe is hidden
