+### zh_vector_push_front()
+
+Adds an element to the beginning of the vector.
+
+**Parameters:**
+
+- `vector` - Pointer to the vector structure
+- `item` - Pointer to the element to add
+
+**Returns:**
+
+- `ESP_OK` - Success
+- `ESP_ERR_INVALID_ARG` - Invalid argument (NULL vector or item)
+- `ESP_ERR_INVALID_STATE` - Vector not initialized
+- `ESP_ERR_NO_MEM` - Memory allocation failed
+
+**Note:** The function allocates memory for a copy of the item and copies the data. All existing elements are shifted right by one position.
