+    Extractor that combines keys and values from two separate extractors.
+
+    The `keys_extractor` and `values_extractor` extract records independently
+    from the response. Their outputs are zipped together to form key-value mappings.
+
+    Each key from `keys_extractor` should correspond to a key in the resulting dictionary,
+    and each value from `values_extractor` is the value for that key.
+
+    Example:
+      keys_extractor -> yields: ["name", "age"]
+      values_extractor -> yields: ["Alice", 30]
+      result: { "name": "Alice", "age": 30 }
