Description
Hello! AmbientCSS is a side project I started 5 years ago because I found the lack of realism in CSS shadows jarring. So, I tried to create a more realistic and consistent shadow system for CSS. It grew too complex and I gave up. Now, thanks to LLMs, I was able to revive it. As such, it's good enough to play with but might not be good enough for production use.

Could you build this?
Yes The author explicitly revived this using LLMs, implementing mathematical CSS shadow/lighting calculations and React wrapper components entirely within client-side code.
