// ### `prefetchTimeout`
//
// When `prefetch` is enabled, this value sets the number of milliseconds
// before The Lounge gives up attempting to fetch a link. This can be useful
// if you've increased the `prefetchMaxImageSize`.
//
// Take caution, however, that an inordinately large value may lead to
// performance issues or even a denial of service, since The Lounge will not
// be able to clean up outgoing connections as quickly. Usually the default
// value is appropriate, so only change it if necessary.
//
// This value is set to `5000` milliseconds by default.
prefetchTimeout: 5000,
// ### `fileUpload`
//
// Allow uploading files to the server hosting The Lounge.
