  // This is a host config that's used for the `react-server` package on npm.
  // It is only used by third-party renderers.
  //
  // Its API lets you pass the host config as an argument.
  // However, inside the `react-server` we treat host config as a module.
  // This file is a shim between two worlds.
  //
  // It works because the `react-server` bundle is wrapped in something like:
  //
  // module.exports = function ($$$config) {
  //   /* renderer code */
  // }
  //
  // So `$$$config` looks like a global variable, but it's
  // really an argument to a top-level wrapping function.
