Case contract

Pick the rate card for a pickup at ts_utc seconds (Unix epoch; day 0 was a Thursday) in a city at offset_min minutes from UTC. Local day index and minute-of-day come from the local time; weekday is Monday=0. Cards are checked in order, windows are half-open [start, end) minutes; a window with start > end wraps midnight and its after-midnight part belongs to the previous weekday. Holiday cards match local day indexes in holidays. Default "standard".

Why this case matters

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