Alerts are shown only when the API returns a source-backed match.

Readings and thresholds stay tied to USGS, NOAA/NWS, or source-backed records.

Observed and fetched timestamps are shown separately when the API returns them.

Unavailable forecasts, alerts, and thresholds are shown as unavailable states.
