Tonight I worked on the party page. I am trying to continue with the side pane metaphor, since it will be important later for other things I want to build.

Since we're building this as scaffolding for the whole app to use, the primary constraint we have to abide by is that all content must be visible and interactive while the side pane is open. I struggled with this so much because that makes the minimum desktop width 1200px, which I suspect is too wide. We will have to work exceptionally hard to make sure the grid portion (the left side) is responsive enough to keep the minimum desktop width a little bit narrower than that.

Other than that, I do like where this is going. Removing some of the team detail information cleans up these pages a lot. The main concern that remains is what to do with the Save/Remix buttons. I wanted to make Save into Like and make it more robust, but as things are right now, I might not have space to.
