+// Null module shim for packages not available in the docs build.
+// These are transitive dependencies of superset-frontend components that exist
+// in the barrel file but are never rendered on the docs site.
+// webpack needs these to resolve at build time even though the code paths
+// that use them are never executed at runtime.
+//
+// This shim uses a recursive Proxy to handle nested property access chains:
+//   import ace from 'ace-builds'; ace.config.set(...) → works (returns proxy)
+//   import { useResizeDetector } from 'react-resize-detector' → returns noop hook
+//   import ReactAce from 'react-ace' → returns NullComponent
+
+const NullComponent = () => null;
+
+// For hooks that return objects/arrays
+const useNoop = () => ({});
+
+// Mock for useResizeDetector - returns { ref, width, height } where ref.current exists
+const useResizeDetectorMock = () => ({
+  ref: { current: null },
+  width: 0,
+  height: 0,
+});
+
+/**
+ * Creates a recursive proxy that handles any depth of property access.
+ * This allows patterns like ace.config.set() or ace.config.setModuleUrl() to work.
+ *
+ * The proxy is both callable (returns undefined) and accessible (returns another proxy).
