### Link Previews

Paste a URL on its own line to automatically generate a preview card:

- **YouTube**: `https://www.youtube.com/watch?v=dQw4w9WgXcQ`
- **YouTube Shorts**: `https://youtu.be/abc123`
- **Twitter/X**: `https://twitter.com/user/status/1234567890`
- **Facebook**: `https://www.facebook.com/user/posts/123456789`
- **Facebook Reels**: `https://www.facebook.com/reel/123456789`
- **Instagram**: `https://www.instagram.com/p/abc123/`
- **Images**: `https://example.com/image.png`
- **Generic**: Any other URL becomes a card with favicon

Note: Instagram Reels, TikTok, Threads, and Vimeo links are treated as generic links and will display a simple card with favicon instead of an embedded player.

#### Deleting Previews

Each link preview has a remove button (X) in the top-right corner. Click it to delete the preview and continue writing after it.
