Agreed - particularly because there is an example of a login box and the screenshot of that is far more prominent than the rest of the design.
I don't think the demo should overpower the landing page.
And then it goes straight into themes. If I'm a Rails developer I'm not looking at theming, I'm looking for a conventional UI system that fits into Rails - stimulus, Hotwire, all that.
As far as I know, this site so far is just a bunch of specialised scaffolds for certain use-cases, but Rails itself has been capable of that the entire time.
