Food barcode lookup with computed Nutri-Score API

Looks up a product on Open Food Facts and, beyond normalizing it, RE-COMPUTES the Nutri-Score nutritional grade (A-E) from the raw per-100g nutriments using the official 2017 points algorithm, then cross-checks the computed grade against the stored one. The value-add: deriving and validating a health metric rather than echoing it, plus a clean ingredient/allergen/nutrition schema. Distinct from data-food (USDA). Answers 'Nutri-Score for this barcode', 'how healthy is this product', 'score this food', 'is this barcode product good or bad for me'.
