Case contract

Zone names are case-insensitive (normalized upper case). A flat fare table keyed "A|B" applies in both directions; a flat fare (0 is a valid promotional flat) is never surged. Otherwise the metered fare is surged (tenths, half up). Airport fees apply separately: the pickup fee of the pickup zone and the dropoff fee of the dropoff zone. Tolls are added last. Return [fare, flat|metered].

Why this case matters

Ride-hailing prices are computed per trip at scale; ordering, unit and boundary slips become systematic over- or under-charging.
