This is likely the biggest thing I'm unsure about for this PR, so I'm going to pull it into a seperate branch so I can merge the system color library in.

I think a better approach for this will be one of two things:
- Have a single next app that covers everything to do with themes (previewing ramps, generated themes, components etc.)
- Create a mono or turborepo that splits things up into packages (system, theme, themes, theme-tool, etc)
