V13.3: Add Ridge OOF + physics hybrid search (raw caps) + area-balanced sample weights + median baseline

V13.2: Add back texture+slope+interaction features, skip residual mode (physics uninformative), fix ET param mapping

V13.1: Fix ET crash + physics NTU->mg/L calibration + param remapping

V13: Physics-first residual learning with correct S2-specific Nechad constants

V12: Literature-grounded physics-ML hybrid (direct log10 target, reduced features, fixed inference)

Add V12 header (full file via API)

V11.1: Fix blend search (exclude broken models), reduce N_OWT=4, robust physics calibration, demote texture features
