Boundary-aligned 2D cross field on a regular grid (QUAD_MESHING_REDESIGN_PLAN §4.4b). The 4-RoSy representation u = (cos 4θ, sin 4θ) is pinned along the aligned polylines and harmonically extended by SOR on the 5-point Laplacian with mirrored (Neumann) grid edges. Hand-written; no third-party solver.
