Reference answer

The system should allow users to submit reviews and ratings for food items and entire orders. Users can also interact with existing reviews by liking or disliking them. All reviews for a specific item should be visible. A rewards program can incentivize high-quality reviews, potentially offering monthly rewards like cash cards based on review helpfulness (e.g., number of likes). The system assumes users are authenticated and that order/item data already exists elsewhere. Media uploads are out of scope.
