PivotTrace Map

Loads field polygons from /public/unified_fields.geojson, joins WagNet devices, and (with a water snapshot + optional public/data/pivot_boundaries.json) can tint pivot rings by April applied depth like the PDF report. Use April depth (report) on the map.

Pivot 16 warning: CRS can be tricky. If it looks offset, re-export with correct CRS metadata.
