• Spatial projection in raw, logistic, and complementary log-log (cloglog) scales.
• Terra-native raster I/O with streaming evaluation for low memory usage.
• Model diagnostics: AUC, variable importance (percent contribution and permutation importance), response curves, and MESS maps.
• Lambda file I/O compatible with the original Java MaxEnt software.
