jyvikoandClaude Opus 5.5 6da3055a1c fem: mortar integration over the edges of 2D models
Segment-to-segment overlap of two edges projected along the secondary
normal (Yang, Laursen & Meng 2005), three-point Gauss-Legendre with the
out-of-plane measure (thickness or 2 pi r) in the weight, over the same
Real scalars as faces so the solver gets exact derivatives.

jyvikoandClaude Opus 5.5 37f338c9e8 fem: mortar segmentation of face pairs with forward-mode automatic differentiation
The overlap of a secondary face with a main face (projection onto the secondary plane,
Sutherland-Hodgman clipping of their triangles, Radon's seven-point rule on the overlap's
fan) and the inverse linear and bilinear maps of both faces, written over a Real scalar so
that f64, Dual (gradient) and Hyper (gradient and packed Hessian, 24 variables) give the
values and the exact linearisation of the segmentation, the normal and the projection.
