Case contract

Input weekly {hours, cash_rate, tips, min_wage (even cents), tip_credit_max}. Tip credit per hour = max(0, min(min_wage - cash_rate, tip_credit_max)). Hours over 40 are paid at 1.5*min_wage minus the same credit. Credit actually taken = min(tips, hours*credit); the unmet credit is paid as makeup. Return [cash_wages, makeup].

Why this case matters

Tip credits are capped by tips actually received and do not grow on overtime hours.
