Native AT Proto support via Standard.site lexicons

About this feature request

While Ghost blogs can be federated to the Atmosphere through Bridgy Fed (either via the RSS feeds or natively with the ActivityPub support), the challenge here would be discovery on AT Proto-native apps like Leaflet and friends. It would be great if these are available via the use of Standard.site lexicions, more specifically the site.standard.publication and site.standard.document lexicons.
