/**
 * Live LA County records lookup endpoint.
 *
 * Used by the /submit form to show a real-time preview of what we know about
 * a typed address — year built, sqft, lot size, assessed value — so the user
 * sees product value before they hit submit.
 *
 * Server-side wrapper around lib/la-arcgis.ts. Cache-first via la_parcel table.
