On Bluesky, a small standard.site marker now appears beside the names of accounts that publish, in feeds and on profile headers. The marker links to the publication's own site, and its tooltip names the publication.
The content script checks only accounts that reach the viewport, at most twenty per page, and the worker reads their public publication records with the same day-long cache the popup uses. It adds no permissions or OAuth scopes.
