/* =========================================================================
   KAIREXA — Design Tokens & Global Styles
   Concept: "kairos" (the precise moment) + "exa" (scale). The brand idea
   is a software firm that ships at exactly the right moment, at scale.
   Signature element: a live monospace STATUS readout used as a recurring
   eyebrow/tag motif, plus a fine engineering-grid backdrop with a single
   two-stop gradient glow. Everything else stays quiet and disciplined.
