/* ==========================================================================
   Born To Influence design system, flattened for static hosting.

   Compiled from the Claude Design export:
   _ds/born-to-influence-design-system-7e11105e.../{tokens,base,styles}.css

   Two deliberate changes from the export:

   1. Fonts are self-hosted WOFF2 instead of Google Fonts plus TTF. Didot went
      from 258KB of TTF to 46KB, Figtree no longer costs a third-party DNS
      lookup and TLS handshake before any text can paint. Approved 3 August.
   2. Didot Bold and Signarita Zhai are not loaded. Nothing on these pages uses
      them: every h1 sets font-weight 400 explicitly, and no page uses the
      script face. Add them back here if that ever changes.
   ========================================================================== */
