Case contract

Input {axles, trailer_axles, height_cm, dual_tires, motorcycle, tolls: [[class, cents]], oversize_fee}. A two-axle motorcycle without trailer is class M. Otherwise total axles = vehicle + trailer: up to two axles is class 1 when under 200 cm and without dual tires, else class 2; three or more is the axle count, capped at 5. Vehicles 410 cm or taller pay oversize_fee per total axle. Return [class, cents].

Why this case matters

Fee engines bill customers in integer cents; a wrong boundary, rounding stage or cap scope silently over- or under-charges.

One recorded failure
