Part.Rotation is cumulative, so rebinding canonical parts with CreateAtOrigin(original, p.Rotation) double-counted the drawing's own rotation, and FromCanonical rotated each part about its Location, which moved it off its slot and out of the work area. Add CanonicalFrame.RebindToOriginal (rotation = part - original program rotation, footprint aligned to the canonical part) and use it in the three places that duplicated the old logic. The MBR only fixes the frame modulo 90 degrees and nest results are not 90-degree symmetric (an L gave 56/43/42/42 parts by orientation). CanonicalAngle.Compute now picks one of the four orientations from the centroid offset; symmetric shapes keep the MBR orientation. Fixes the three NestInvarianceTests.
