To me it reeks of Claude. The same yellow/brown tint.

But I might be wrong:

Good eye on the colour palette, but that was actually a deliberate design choice. I found the warm ivory theme idea on Dribbble, used ChatGPT to generate mockup images of how it would look applied to HomeOS, and then used Claude to implement it. My family picked it over a couple of other options we tried. Fair point though I can see how the warm tones might look familiar if you've seen a lot of Claude-generated UIs.
