POST /api/locus-seismic-design
USGS seismic design parameters for an address. Perfect for: 'seismic design category for an address', 'Ss and S1 for a site', 'earthquake design values for a property', 'NEHRP seismic parameters', 'PGA for a location'. Returns USGS NEHRP-2020 design data at a US point: Ss, S1, PGA, SDS, SD1, site class, risk category, and seismic design category where USGS has finite values. Engineering hazard data, not a safety verdict. Charge-free when the address fails or USGS has no value.

EVIDENCE
Each record has an exact-route quote outcome. Unresolved templates and potentially mutating methods are labeled instead of being invoked without provider-specific test input. A quote is still separate from a settled paid call.
