// ANISOTROPIC MATERIAL-COMPENSATION SAMPLER
// The top row uses legacy scalar widening. The bottom row uses the same
// authored bars and pull magnitude projected through grain/stretch intent.
// Compare each vertical, diagonal, and horizontal pair after hoop release.
// SEW-OUT ASSUMPTIONS (4x4 hoop): two-way stretch knit, one cutaway
// stabilizer, polyester 40 wt, NM 75 ballpoint embroidery needle, no topping.
// The 0.6 mm pull value and anisotropy are experimental, not profile defaults.
