"description": "`meshc` combines a `mesh`-style wireframe surface with contour lines projected onto the base plane. In RunMat the returned handle is the primary surface handle for the wireframe component, while the contour overlay is attached as the secondary composite plot content.",
"behaviors": [
"`meshc` shares the same wireframe surface semantics as `mesh` for the primary surface object.",
"The returned handle is the surface handle for the wireframe component of the composite.",
"Contour overlays are produced through the shared contour path.",
"View state, colormaps, and subplot-local metadata all flow through the shared axes model.",
"GPU-aware execution applies where supported to both the surface and contour sides of the composite."
