Visual regressions on the index page:

- `Supporting academic collaboration` is a different font, causing it to be more bold
- The spacing around `Supporting academic collaboration` is a bit off as well compared to the previous UI
- The `search` label is bold
- The rounded corners on the search field are no longer there
- The padding around the Go button and the margin around the overall search pane are a bit off
- `Authoring experiences`, etc. are a different font
- The page content should have some left and right padding when looking at it in small mode. Currently, the video and search box are too close to the side of the page
- The `A powerful new way ...` block is not full width when looking at it in small mode
- Can we allow the page to become smaller than its current min-width? I don't see any obvious reasons to not allow for that.
