MathRow

An explicit grouped atom. Children align on their math axes and keep their order; the row adds no inter-atom glue.

Property	Default	Meaning
children	Empty	Elements or TeX strings; each string becomes its own spaced MathText.
klass / left / right	"mord"	Classes exposed by the complete group.
strut	false	Add a one-em minimum line box centered on the axis.

Common font, color, and sizing properties follow Gum units. Math preserves separate logical advance, outline ink, baseline, and math-axis guides. See math authoring for supported TeX and font setup.
