Query names are case-insensitive (`limit` / `Limit`). `sortBy`: `Id` · `Name` · `Price` · `CreatedAt`. `sortDirection`: `Ascending` · `Descending`. Empty cursor + `pageDirection=Backward` is the last page. **Cursors are opaque** — pass `NextCursor` / `PreviousCursor` back unchanged; do not construct them.
