* Lays metric cards out as a wrapping row of vertical columns, one column per [MetricGroup].

*

* Related readings (a channel's voltage and current, a temperature and its dew point) stay stacked together and share a

* column width; unrelated single readings are packed into columns of [PACKED_COLUMN_HEIGHT] so the grid keeps an even

* height. Both together pack the cards far more tightly than a flat row of independent cards — see issue #4507.

*

* [valueColor] overrides a card's value text color, for metrics that are color-coded by severity; returning null keeps

* the [InfoCard] default.
