Lightning distance

Commercial credentialed 65-endpoint Weather API. For `/lightning`, standard access returns global real-time pulse records from the past five minutes, with a 100 km maximum radius and up to 1,000 records per query. The separately available Lightning Enterprise add-on preserves the same product boundary and adds client-defined polygon/bounding-box searches, circles up to 500 km, up to 24 hours per request, archive access from 2016 to the present, and up to 50,000 records per request with `skip` paging. The endpoint emits pulse-level observations, not native area-density, seasonality, denominator, climatology, or completeness outputs. Other Weather API endpoints remain inside this Source but outside this audit.
