   Identity: near-black violet, one continuous gradient running violet -> cyan
   -> pink across every surface. Glass cards, hairline borders, soft outer glow.
   Type: Sora for display, Inter for reading, JetBrains Mono for data.
   The recurring motif is a live neural mesh: drifting nodes, drawn edges.
   Motion: everything below is decorative and gated behind prefers-reduced-motion.
