- gate reply inclusion in JSON-LD comment[] on hideReplyLabels and
hideEmbedLabels so abusive/spam reply text isn't surfaced into the
parent post's structured data
- add author identifier (DID) to post/comment author Person nodes so
identity survives handle changes (mirrors profile Person)
- lift og:video block out of {% if imgThumbUrls %} so videos without
thumbnails still emit og:video tags
