nx_breeder_lab.nx -- THE GENETICS LAB SCREEN + the tooth that proves the science is VISIBLE. Emits a real game screen: two parents, their Punnett square, and the litter they actually produced -- and then MEASURES the rendered litter's visible phenotype ratios against the Punnett prediction. That measurement is the difference between "we have genetics" and "the player can SEE genetics". Educational payload, on screen: genotype notation (Hh), the 4-cell square, the predicted odds, and the observed count -- the exact loop a biology student runs by hand. license_tier: ORIGINAL
