What does this PR do?

Draft of a small home page refresh exploration proposed by Chris. This doesn't touch any broader content restructuring aside from taking a "small step" towards a side bar navigation

Some to do's:

• For the "Search" experience, using keyboard to move down through search results does not keep the active item in view. This could be a Grommet bug.
• Connect with Julia to get her thoughts on the structure.
