Rich summary stats

Public metadata — no API key required. Jurisdictions breakdown, events by type/severity, feature counts, last sync times.

Freshness: the response is cached for 5 minutes. events.total — the count of every event row ever stored, as opposed to events.active — is refreshed hourly rather than with the rest, because it is a full-table count and moves by a fraction of a percent per hour. It is exact, not estimated; only its refresh interval differs.
