+// Hide the filter category selector when there's only one filter.
+// We use CSS instead of TypeScript prop changes because PatternFly's
+// DataViewFilters component doesn't expose a prop to hide the category selector.
+// This CSS-only solution avoids forking or patching the upstream component.
