What's the best way to add my own custom theme using Pink Design?

I started playing around with overriding some theming variables, like --color-pink-text, for example, but it didn't seem that doing that alone was updating any component or utility class colors.

Also, I started inspecting the pink stylesheet by searching for instances of .theme-dark to see how that was done, but there are way too many instances (over a hundred, I believe.) So, I stopped going down that path.

I really want to use Pink Design for more than hobby projects, but I just want to be able to customize/override colors, like borders, corners, spacing, typography, etc. to fit the branding style I'm going for. But, mostly colors, at the very least.

I searched for articles and videos to no avail, and here I am. I'm pretty much new to Discord, but this seems like a good place to get some direction on this, or at the very least find out that what I want to do isn't possible with an appropriate amount of effort.

Of course, any advise on this would be extremely appreciated. Thanks!
