/* ============================================================================
   CORTEX / CHAOS LABS — LANDING-PAGE DESIGN TOKENS
   Distilled verbatim from ChaosLabsInc/company-website @ main
   (src/styles/globals.css, keyfeatures.css, tailwind.config.ts).

   This is the MARKETING-SITE token set — distinct from the Chaos AI *app*
   design system. Key differences:
     • Canvas is the dark "space" navy (#0B101C); marketing sections alternate
       dark <-> white. Text default is WHITE on dark.
     • Type roles are swapped vs. the app: INTER is the primary/body face,
       AT AERO is the secondary/display face, AEONIK FONO is the mono/label face.
     • A responsive --cell grid drives the column-rule background pattern.
     • Surfaces are glassy: .card / .browser use layered inset shadows + blur,
       never flat fills.
