I am still confounded by the fact that to "be standard.site" you have to put extra data on a PDS. And this is done just so links get nice embed cards on Bluesky?

To give my normal "standard web" website a nice embed on Bluesky I have to add each and every article on Bluesky?

How does this make sense? Why is this desirable over data that's entirely in the page itself? What am I missing?!
