External CSS can target these via atproto-mentions::part(<name>) { ... }.

PartWhat it is
head / grid / actor / actor-avatar / loadmore / emptySame parts as all actor-grids.

Richtext facets are ATProto's structured-annotation format. A mention inside post text is a #mention feature inside the facet's features array. The full index path is

app.bsky.feed.post:facets[app.bsky.richtext.facet].features[app.bsky.richtext.facet#mention].did

The [$type] brackets tell Constellation which element of the array to walk — facets and features are both discriminated unions, so disambiguation matters.

<atproto-citations> is the URL-linking sibling (posts that linked to your blog). <atproto-backlinks> shows both alongside every other inbound link.
