app.zeens.eventComment

A comment (question / feedback / discussion) on an app.zeens.event, written to the commenter's own PDS. Bluesky replies require an app.bsky.feed.post parent, and an event isn't one, so events use this dedicated record (same rationale as app.zeens.post). A `parent` strongRef threads replies, letting the organiser respond in-line. Counted into the event's reply_count. Carries the app.zeens.v marker.
