// The flat "all comments" view (?flat=1) paginates ThreadMeta.AllReplies so
// every comment is reachable, unlike the recursive threaded view which
// truncates a large thread. Each flat page renders one <gno-foreign> block
// per comment, bounded by pageSizeFlat (50). With 60 comments the flat view
// spans 2 pages; the last comment is reachable via newest-first (desc page 1)
// and via page 2.
