A clearer way to understand this project is to look at their graduated proposals:

* https://open-ui.org/components/popover-hint.research.explain...

* https://open-ui.org/components/popover.research.explainer/

* https://open-ui.org/components/invokers.explainer/

* https://open-ui.org/components/accordion.explainer/

The goal is to take common web UI patterns that are good UI but require fiddly custom JS today, and get them standardized and into browsers.
