Two more user-facing modes on top of the address endpoint:
/compare — side-by-side briefings for two queries, useful
when picking between candidate parcels or
comparing two neighborhoods.
/register/{class} — pre-computed exposure for an entire asset
register: NYC DOE schools, NYCHA developments,
MTA subway entrances. The JSON ships baked
(built offline by register_builder), so the
UI is just paginated rendering — every row
shows the same paragraph + tier the address
mode would produce.
Asset loaders normalise each register's source GeoJSON into the
common (name, lat, lon, props) shape register_builder expects.
