Suspense

I misunderstood how Suspense works a little. This is actually very cool, allowing us to do things like wrap the whole right-sidebar in a Suspense boundary so the whole sidebar is hidden until all components are loaded.

It's important to understand that a lazy component MUST have a Suspense boundary above it somewhere in the tree. For most UI routes, the router helper will add it, but in cases like the ProfileHoverCard it needs to be wrapped, etc.
