Settings & data sources
Keys are stored only in this browser (localStorage). Leave blank to use the manual ledger — the app still works without a single key.
Free sources already wired in (no key needed): US Census geocoder (address → coordinates + census tract), FEMA National Flood Hazard Layer (flood zone), USGS elevation, Cuyahoga County parcels (owner, assessed value, land use, acreage). These run direct from the browser. Clicking Pull sources on the ledger calls them automatically and tags each result Tier A.
Paid/trial sources: ATTOM, Regrid, Shovels and Zoneomics need a key AND a serverless proxy (CORS-blocked from the browser). Paste a key here for the record; the proxy is the next build step.
