This is impressive Matt, and I love the design system GDS has developed, but I'm not sure they want non-government services to use the system. From the second link you posted:

> Use this design system to make *government* services consistent with GOV.UK

Emphasis mine. Are GDS aware of this work? I am in no way affiliated with GDS by the way.

I'm always wary of this kind of thing not being on a gov.uk domain, which in this case is entirely appropriate because it's not in anyway official or endorsed by GDS. Not for any direct phishing/crooks concerns as raised above, but because it waters down the impact of this kind of thing always being on gov.uk domains.

Edit: I'd be _very_ surprised if GDS don't take issue with you having "GOV.UK" in the name given that it is no way associated with gov.uk
