It looks like this project has been abandoned for over a year. There's quite a few rough edges that stand out pretty distinctly: some buttons have a pressed state, others don't. Some controls have transitions or animations, while others which I'd expect to have transitions do not. Spacing and margins seem off (even the tiles on the Examples page). Some of the styles on the Layout documentation are broken due to specificity issues. Sizing is mixed: select boxes are very small compared to text inputs, while the switch control is absolutely massive. Most of the text is very large, but the mobile tabs' text is almost unreadably small. But this is a small personal project, it seems, and nobody is expecting high-end results.

But here's the thing: the project is sponsored. Moreover, the website of the company that sponsors the project is down. Which, for a mostly-abandoned project, isn't surprising. But if you look up Fractal Technologies online, the two employees other than the CEO have been working there for under two years. Moreover, Fractal has been a sponsor since March 2021 [0]: there have been only a handful of commits since the sponsorship began. It's curious that an "IT Services and IT Consulting" company specializing in blockchain, AI, and IoT which doesn't seem to have a website would sponsor a project which is mostly unmaintained. The more I read about the business and the employees, the more questions I have.
