Changes: crop-area grids clipped to Mexico with INEGI boundaries; 46 crops grouped into 11 categories; cells with at least 10% modelled crop coverage selected; dominant groups selected; adjacent cells merged; center-free clipped fragments omitted; representative crop label anchors and query values derived. These are modelled crop distributions, not observed field boundaries. No institutional endorsement is implied.
