Check a home recipe for allergen cross-contact

Inputs: [RECIPE], [ALLERGENS TO AVOID], [KITCHEN SETUP]. Trace ingredients, labels, utensils and shared surfaces. Mark every unknown product or preparation step as unverified; suggest an alternative only when its ingredients and cross-contact controls can be confirmed. Output: An ingredient audit, clean-workflow checklist and questions for the diner. Check: Never label a dish allergen-free from its name or this desk review alone. If essential information is missing, identify it rather than guessing.
