-## How It Works
-
-1. **Instant** (<1s): Pre-aggregated H3 res4 summary (580 KB) → 38K colored circles
-2. **Zoom in**: Automatically switches to res6 (112K) then res8 (176K) clusters
-3. **Zoom deeper** (<120 km): Individual sample points from 60 MB lite parquet
-4. **Click**: Cluster info or individual sample card with full metadata
-
-Circle size = log(sample count). Color = dominant data source.
