/* Shard Superintelligence Lab, Peer-to-Peer AI: the whole design system in
   one file. Self-hosted Geist (font-src 'self'), no frameworks, no inline
   styles (style-src 'self').

   Principles: the live network is the one bold, moving thing; everything
   else is still. Structure carries meaning: only the surface you act in
   (chat, signup) is elevated, readouts are ruled strips, numbers mark the
   one real sequence. Colour carries role: iris = compute being given
   (donors, primary actions), quartz = tokens in flight, green = live only.
   Mono is for identifiers (device, ticket), never for labels. */
