Duolingo Design Guidelines

I'm proud to announce the launch of the new Duolingo Design Guidelines, built alongside the Duolingo Design System (DDS)

I also finally found the time to redraw our wordmark, making it more geometric and visually balanced, and banishing the dreaded 'duoLingo' misinterpretation once and for all.

Thanks to our Staff Designer @Gregory Hartman for helping shape Duos face and the blueprint style, and our Chief Designer @Tyler Murphy for guiding the guidelines themselves!
