/* Ground Orbit Networks — shared stylesheet
   ------------------------------------------------------------------
   2026 redesign. The system: a graphite orbital segment, a paper ground
   segment, and a steel-blue path between them. Serif headlines carry the
   institutional voice; the mono face prints anything the network itself
   would print — waypoints, telemetry, dates, step numbers.

   All three faces are self-hosted from assets/fonts/. The site makes no
   third-party requests, and that is deliberate — see CLAUDE.md.

   Source Serif 4 and IBM Plex Sans are variable fonts: one file each,
   carrying the whole weight axis. The per-weight @font-face blocks below
   therefore point at the same file and pin a single weight, which is what
   Google Fonts itself served and is what the browser instances. Adding a
   weight the design needs later means another block, not another file.
