+/**
+ * Lightweight shim for @superset-ui/core.
+ *
+ * Components in superset-ui-core/src/components/ self-reference the parent
+ * package for utility imports. This shim re-exports only the specific
+ * utilities they need, avoiding the full barrel file which pulls in heavy
+ * dependencies (d3, query engine, color scales) that cause OOM during the
+ * docs build.
+ *
+ * When adding exports here, verify the source file's imports don't cascade
+ * into heavy modules (connection/SupersetClientClass, query/types, etc.).
+ * Only add leaf-level utilities with minimal transitive dependencies.
+ *
+ * Exports that can't be shimmed safely (e.g. getClientErrorObject, which
+ * pulls in connection/types → SupersetClientClass) will produce
+ * ESModulesLinkingWarnings at build time — these are harmless.
