Task 382: Infrastructure Orbital Diagram

Status: DONE

Summary

Add a solar-system-wide orbital diagram to infrastructure.md showing:

• Station locations (Mars, Ganymede, Enceladus, Titania) along Kestrel's route
• Inner sphere / outer sphere governance boundary
• Kestrel's route as transfer arcs
• Staffing annotations

Currently infrastructure.md has two bar charts but no spatial diagram. The cross-episode full-route-diagram doesn't cover stations or governance zones.

Rationale

• CLAUDE.md: "Prioritize visual explanations"
• Infrastructure report analyzes spatial distribution of stations and governance, but has no map
• Existing orbital-diagram component supports this without code changes
