   COHESIVE DARK CLOSING AREA (home)
   A document-anchored dark sheet that rises from the bottom as you
   scroll into the lower part of the page, so the closing region reads
   as one continuous dark surface (CTA band + footer) rather than a few
   detached dark elements. Injected + positioned by eipme.js (top edge
   anchored just above the closing block), so the top fade always blends
   harmoniously into the page background above it.
