// Visibility state of a Story within the session shell.
// This state describes how a story should be displayed within the session shell,
// regardless of whether the story is in focus or not. Focus state and
// visibility state are orthogonal concepts.
// E.g A story can be out-of-focus and be in IMMERSIVE state at the same time
// if a user was playing a video, exits, then re-enters the story. The
// expectation in this scenario is that the story is in IMMERSIVE state upon
// re-enter.
//
// All state transitions are possible.
enum StoryVisibilityState {
    // Default state for a story.
    DEFAULT = 1;
    // Full-screen user experience, e.g. playing a video.
