Review notes

Context from the listing review and editorial research.

UPDATE existing row by exact Name Trinka (id 488, slug trinka, batch-12). Canonical site trinka.ai (Enago). Distinct from Review-it, PeerReviewAI, and Grammarly. Prefer annual vs monthly math when quoting Premium. Confidential Data dollar display is inconsistent across official UI and aggregators; do not hardcode without checkout confirmation.
