To-do: auto fetch ATproto/Bluesky comment threads from `bskyPostRef` in `site.standard.document` lexicon.
This issue proposes automatically fetching ATproto/Bluesky comment threads from a `bskyPostRef` within the `site.standard.document` lexicon. The core challenge is that the author has not yet found a `site.standard.document` lexicon that actually includes `bskyPostRef`, making the implementation currently infeasible.
