Northeast City and State Lane
The Northeast set works because each surface has a different operating role: Boston for a larger city base, New York for NYC-first state expansion, Providence for compact city depth, and Rhode Island for statewide area choice.
Boston and Providence are city decisions
Open them when the traveler already knows the destination and needs base, dining, arrival, or district choices.
Rhode Island and New York are state-capable
Rhode Island is already statewide. New York is structured as a state hub, but it should stay NYC-first until Hudson Valley and Long Island have verified records and guides.
