Gaza Drift Physics - Corrected Analysis
=======================================

Proper physics-based analysis with:
1. Clear water vs land boundaries
2. Realistic trajectory in water only
3. Vector force visualization (wind + current)
4. 5L jerry can option analysis
5. Close-up views of actual drift area
