+
+**Added "Last updated: Mon D" to creators browse rows and subtle date stamps on homepage recently-added cards**
+
+## What Happened
+
+Added last_technique_at to the frontend TypeScript interface, rendered it on the creators browse page after stats (only when non-null), and added created_at dates on homepage recently-added cards with muted styling. Rebuilt and deployed the web container on ub01.
+
+## Verification
+
+TypeScript compiles clean. API returns last_technique_at with both null and non-null values. Browser verification confirms dates appear on creators page rows (and are absent for 0-technique creators) and on homepage recently-added cards. All dates use short format (Apr 2, Apr 3).
