/* =========================================================
   Digimarketlabs — Design System v2 "Signal"
   Direction: premium enterprise SaaS vendor — the visual
   register of Linear / Vercel / a top-tier B2B consultancy.
   Signature device: a node-and-edge "citation graph" — the
   literal shape of what GEO/AIO optimizes (your content
   becoming a cited node in an answer graph). Confident dark
   hero with a soft aurora field, restrained cobalt+violet
   accent, brass used only as a rare premium marker.
   No webfonts, no external requests — system stacks only.
