Detailed Description

One cell of a mixed triangle/quad mesh, pre-split for the reconstruction (workplans/TRI_QUAD_MESHING_PLAN_2026-09-06.md).

Built once per geometry rebuild from mesh::cellGeom so the quad's sub-triangles are the SAME two the engine's VFR storage model uses (Begnudelli & Sanders 2007 diagonal). A triangle has nSub == 1 and sub[0] == {v0,v1,v2}; the areas are only consulted for a quad.
