   Hadal Nexus — digital product company site
   Concept: scrolling down is a descent. The background darkens from the
   surface to the hadal floor; a depth gauge in the left margin tracks the
   dive; the deepest point (Hadal) is where the products + company live.
   Palette sampled from the brand logos.
