   Fixed over the top of the hero photo. At the top of the page it is clear,
   with a white wordmark on a soft dark tint; once the page scrolls
   (.is-solid, set in presale.js) it settles into a frosted off-white bar, the
   wordmark turns black, the bar tightens a little and a hairline grows out
