- Composite GIF export — Export multi-radar groups as composited GIF animations (1920x1080)
- Bilinear interpolation renderer — GR2Analyst-quality smooth rendering with gate and azimuth interpolation
- Dynamic resolution scaling — Render resolution adapts to zoom level (1024/2048/4096px)
- 3D cross-section view — Perspective-projected vertical cross-section with drag-to-rotate, ground plane grid

Improvements
- 4-panel view — Now uses smooth renderer, custom color tables, and dynamic resolution
- Cross-section click fix — Tool clicks (cross-section, measure, sounding) no longer conflict with map panning
