   WEBLINE.LK v4 | "The Swarm"
   Night-ocean world, one live WebGL swarm (assets/js/swarm.js) layered
   between photographic plates and real HTML. Cabinet Grotesk display,
   Geist body, Geist Mono labels. Azure = Webline/AI, teal = Codexa,
   violet = Nyoxa. Radius: 10px controls, 18px surfaces, 999px pills.
   Layering: section plates (z 0) < swarm canvas (z 1) < content (z 2).
