[uncenter]

Possibly closes #6. Ref catppuccin/whiskers#66.

Why is this a draft? It should be merged even if it doesn't fix the issue.

ANSI colors aren't even merged as part of Whiskers.

Really? I remember seeing a issue in the Windows Terminal repo that's at least 6 months old by now asking for the new ANSI colors.

That's your issue, and yep ANSI colors were only released at the end of October and haven't made their way into our tooling or ports.

I forgot I made the issue because I haven't checked it in so long, I only remembered it exists. So I got really lucky and unlucky at the same time because the last time I checked the progress on ANSI colors they were already in the style guide and I knew the branches mentioned in the repos existed so I assumed whiskers already had full ANSI support.
