/* ============================================================================
   FAIRTAP — event connection infrastructure. Standalone design system.
   Mission-critical control-plane aesthetic: cold navy infrastructure surfaces,
   infrastructure-blue as the working accent (APIs, data movement, control),
   FairTap orange reserved for physical connection / brand / CTA (~5% of screen),
   verified-green for healthy/synced, warning-amber + failure-red for conditions.
   Harder geometry, dense real system information, mono only for identifiers.
   No framework. CSS transforms/opacity + WAAPI + SVG only.
