   BOREALIS CORE DESIGN SYSTEM v1.0.0
   The single source of truth for all Borealis Protocol visual design.

   Designed with Jony Ive DNA: radical simplicity, quiet confidence,
   honest materials, obsessive consistency.

   Usage: <link rel="stylesheet" href="/borealis-core.css">
   Each site adds a body class for variant: body.site-protocol, body.site-terminal, etc.
