Research direction

The issue requests support for Vue functional components. Currently, the implementation uses $options which is only available in stateful components. To add support, you need to modify the library to detect functional components and handle them differently. Look at Vue's documentation on functional components, especially the render function context. Then examine the source files in the styled vue repo, likely in the main index.js or src folder, to understand how styles are applied. Check if there are any existing PRs or discussions for inspiration. Consider using a different mechanism, like injecting a prop or using the component's context, to make styles work without $options.
