for reference -- we could use this component:

https://ui.shadcn.com/docs/components/navigation-menu

We'd only need 3 links and the titles/subtitles for each would be:

Teams (/teams) Insights to validate and share the impact of open source to your organization.

Maintainers (/maintainers) Grow and celebrate your open source community.

Contributors (/contributors) Start the path to your next contribution.

What should the Features tab go to? With #209, it will redirect to /#features which wouldn't exist, since it's been moved to /contributors.

we can just kill the features link
