Mesh2D

Property	Default	Meaning
xlim	[0, 1]	Domain for vertical grid lines
ylim	[0, 1]	Domain for horizontal grid lines
xticks	5	Target count or explicit x values / labeled pairs
yticks	5	Target count or explicit y values / labeled pairs
stroke-width	em(1/16)	Grid thickness, relative to inherited font size

Combine HMesh and VMesh. Supply xlim, ylim, xticks, and yticks; each domain defaults to [0,1] and each count to 5. The graph provides mapping; these props provide tick values. Plot automatically synchronizes grids and axes.
