   GN Devices — Electronic Torque Wrenches
   Design system: graphite/steel instrument base + single torque-orange accent.
   Native CSS, zero build step. Locked page theme (light/dark), one accent,
   one radius scale, mono-for-data type signature.

   Fonts: system grotesk + system mono (fast, no external requests, on-brand for
   a precision-instrument voice). To upgrade later, self-host Geist / Space
   Grotesk and swap --font-display / --font-mono below.
