How are fallback colors calculated for out-of-gamut tints and shades, and where can I find this functionality in the code?

Hi there. I'm trying to write a script for Adobe Illustrator, and I want to use the OKLCH color space. I've run into some out-of-gamut problems when trying to generate some specific hues, and I wanted to ask for your help in pinpointing the part of the source code that handles these fallbacks just like in the web tool. Thank you very much!

We use toGamut('rgb', 'oklch') from Culori
