T8b949e/**

* Unit tests for the air-quality chart's value extraction ([AirQuality.getValue]).

*

* Locks the BUG B fix: a present-and-zero reading (a PM sensor in clean air reports 0 µg/m³) must be plotted, while a

* genuinely absent field stays null so the metric is neither charted nor offered as a selectable chip. Also pins the

* assumption that a partial-sensor node (e.g. CO2 only) leaves the other fields unset/null rather than zero.
