   .hero is a pure scroll-distance spacer: its fixed-position child covers the

   shared/hero-scroll.js), then crossfading into #app-section, whose negative
   margin-top (set from JS, matched to the fade portion of the scroll track)
   pulls it up to physically share screen space with the fading hero instead
   of just appearing once scrolled past — that overlap is what makes it read
