Type Alias LinkPreview

Link previews in UNET posts: the apps append the preview to the post text as a last line, \u200C\u200CLP{"url":…,"title":…,"description":…,"image":…}, and put \u200B before a link that must not get one. post.content therefore contains that line; split it off before showing the text.

type LinkPreview = {
    url: string;
    title?: string;
    description?: string;
    image?: string;
}
