/* Nexus CX Partners — design system.
   "Advisory brief": calm, consultative, buyer-side. Warm paper, rich-black ink,
   restrained violet accent, hairline rules, brief-cover cards.
   Type: Plus Jakarta Sans (UI/display) + Source Serif 4 (standfirsts, callouts only).
   Signatures:
     · the hero exhibit — an inline-SVG "evaluation matrix" plate (a buyer's-brief
       cover) sitting over an ambient "nexus" field of drifting connective nodes;
     · the advisory-standards band under the hero (how we work, on equal footing);
     · brief-cover hover (violet keyline + 2px lift);
     · the article dossier (sticky sidebar, elevated with an evaluation lens);
     · step-connector hairline that draws in with the content;
     · a slim violet reading-progress bar on articles.
   One canonical file per brand: design tokens + component styles. */
