Sharing and link previews
What people see when you post an Interartive link.
Share gives you a link that shows a moving preview where the app supports video previews (Facebook, LinkedIn, Discord, Slack, Telegram, iMessage), a playable card on X where it is allowed, and a clean picture card everywhere else. Pinterest gets a tall pin image.
Pasting a link into WordPress, Notion, Medium, Ghost or Discourse embeds the playable experience when its creator allows embedding.
