How do zero-clearance hinges help with fridge door swing?

Zero-clearance hinges allow the refrigerator doors to open fully even when installed close to walls or cabinets by shifting the door's arc away from the frame. This design minimizes or eliminates the side clearance usually required for door swing. They are critical in tight spaces where the total opening matches the fridge width. Confirm hinge specs because not all models achieve true zero-clearance.
