   TOP FADE
   Fixed strip across the top of the viewport, behind the floating
   nav (z 49 < nav z 50). Background colour is driven by
   --top-fade-color which js/scroll.js updates to match the
   section currently sitting under the nav. Fades to transparent
   via a mask so the boundary with content below isn't a hard line.
   Colour crossfades smoothly between sections.
