+- **Duplicate columns** — Protocol and Pool columns on mixed-driver clusters (tns-csi + rook-ceph) are now merged into a single shared column rather than duplicated; whichever plugin loads first owns the column and the second merges into it
+- **Plugin settings name** — settings entry now registers as `tns-csi` instead of `headlamp-tns-csi-plugin`
