From this fetch. Not Bluesky’s preview.
Bluesky preview
Bluesky’s posts guide reads og:title, og:description, and og:image, then stores them on the post. The title is at most 300 graphemes and the description at most 1,000, from the external embed lexicon. The guide does not publish a crop. This card uses a 1.91:1 frame and says so. A relative image with no :// is joined by appending it to the page URL, which misses a root-relative file such as /og.png.
The card is saved when the post is written. Changing the tags later does not update that post. This page reads the live HTML. It does not edit posts, and it is not a Bluesky product. A paid check draws this Bluesky card from those three tags. Bluesky link preview
