A web story rail with a full-screen player that supports image, video, and quiz slides inside each story.

The Webstory widget starts as a horizontal rail of story thumbnails and titles, then opens a vertical full-screen player when a user selects a story.
Each story can contain image slides, video slides, and quiz slides. The player manages progress bars, play or pause state, video mute controls, and movement between slides and stories.
The player also preloads the current and next slide resources so images and videos are ready as the user moves through the sequence.
The webstory widget requires SyncCMS to be enabled and expects the experience config to provide a `stories` array. The container itself uses the experience ID and can optionally toggle the dark body styling.
