Beautiful design! I want to say as a maybe helpful review point that I see overlapping silk in a few spots. Ideally it would be nice to clean that up, possibly removing all designators which for my personal preference would work, but some people might like to see those. Also I would choose a more playful font for the back text but I like playful. This is an excellent project, nicely done! I’m doing a lot of RP2350 LED work right now, I’ll have to see if I can run your code on the pendant I am designing.
