Ref T5240. This needs some more work but maybe kick the tires on it and see how it feels?
Basically just JS atrocities:
- Move the header nodes around in desktop vs mobile to give us fixed headers.
- Resize stuff all the time in JS.
Things that are kind of bad:
- Vertical scrollbar is odd and not easily fixable. Maybe just, uh, hide it completely?
- I ungood'ed some of the design.
- You can't drag cards out of the board area. This doesn't work at HEAD either but needs to work before we can do the drag-to-a-tab UI from M1450.
- Icon nav is bleeding into the board now because of reasons.
