// Exclusive Elsewhere Script
// Modifies the behavior of the Jellyfin Enhanced Elsewhere functionality
// Adds custom branding when the item is not available on any selected streaming services
//
// If you want to add an icon to the text you can do so by targeting the "exclusive" class.
//
// For example:
// .streaming-lookup-container a.exclusive::after {
//     content: '';
//     background: url(/path/to/icon.png);
//     background-size: contain;
//     background-repeat: no-repeat;
//     width: 25px;
//     height: 25px;
//     display: inline-block;
//     margin-left: 0.5rem;
// }
