## Goal
Enable aggressive, confident experimentation with Groups as a vehicle for user retention by refreshing the home feed screen to use modern design system and UI.
## What needs to be done
Refresh the home feed layout for web + mobile app using the modern design system.
Include a solution for managing settings for the group.

Assume that functionality available on the members list screen can continue to be served by the existing page without refreshing it, since that page isn't critical to Groups usability for most users.
