feat(globe): satellite-to-ground beam visualization#1342
Merged
Conversation
Replace plain footprint rings with Three.js beam cones radiating from each satellite's orbital position down to the ground. Uses 8 ray lines per satellite in a fan pattern with a semi-transparent cone fill, color-coded by operator nation. Batched into 2 draw calls total (1 LineSegments + 1 Mesh) for all satellites, keeping GPU overhead negligible (~5K vertices). Beams toggle with the satellites layer and clean up on destroy.

Summary
Before/After
Before: Small dots at orbital altitude + tiny ring on ground (hard to tell these are satellites)
After: Visible beam cones from satellite to ground, similar to professional ISR visualization tools
