I love this idea for CMS related content and layout. I question the overloading of the 'Canvas' tag but love that you've spent time grooming the projects structure and documentation. The best possible starting blocks to push off from for onboarding trust and quality from developers looking to including such a library.
I would like to note that the `Canvas` React component should not be an issue to the HTML `canvas` element. However, I can definitely understand that it might look confusing to some. At the moment, it is still the most descriptive name that I can think of for what it does.
Nevertheless, I'll keep this in mind and I'm open for suggestions for better naming alternatives.
