Replace the label text with ‘OpenAI’ in the same elegant black serif typography. Add a delicate sterling silver chain draped naturally around the bottle neck holding one small dainty pendant: a miniature chatbot speech bubble icon with three dots, rendered in refined high-fashion jewelry aesthetic, small and dainty like a Tiffany charm.
