   BACKGROUND LAYERS
   Hand-drawn construction artwork (SVG), held far back.
   Depth comes from three things stacked:
     1. an engineering grid, nearest the surface
     2. illustrated architecture, further back
     3. the skyline art's own three internal depth planes
   Every layer lives on a ::before/::after at z-index 0, so its
