/* Boot loader: the static loading screen in the page markup (#boot-loader in client/index.html and the Reddit
   game.html). It shows before any script has run and looks like the app's LoadingScreen (menu.css), which takes
   over once the UI modules are in; main.js then fades this one out. Self-contained: no variables from base.css,
   which may not be loaded yet. */
