   Navisurg Vision — design tokens

   Ported from the Claude Design project "Navisurg Vision Design System"
   (_ds/navisurg-vision-design-system-edf8dd39/tokens/*.css). Values are the
   design system's; treat this file as generated and change it there first.

   One deliberate difference: the design system pulls DM Sans and JetBrains
   Mono from Google Fonts with an @import. Here all three faces are served
   from fonts/, so the page needs no third-party request to render — nginx
   already caches woff2 for 30 days (see nginx.conf).
