Redesign sponsor section

[Ceasar]

This is a tricky problem to solve:

• Sponsors who gave us more should be given more prominence
• Some sponsors are more cool than others
• Some sponsors have background colors that contrast harshly against the white background

It may make sense just to establish prominence by directly labeling the groups rather than doing it by size. It's unclear, but it's a problem that needs to be solved.

I think I like this design: . We can mark Venmo (and the DP) as the main organizers, and then list the rest of the sponsors on the side
