    Given a vehicle's current odometer reading, determine the next palindromic mileage checkpoint for scheduling maintenance, where a palindromic reading reads the same forwards and backwards. The system must identify the smallest possible palindrome number that is greater than the current mileage reading to establish the next service interval.
