Box constructor and derived properties (Right, Top, Center, Translate, Offset) had Width and Length swapped — Length is X axis, Width is Y axis. Corrected across Core geometry, plate bounding box, rectangle packing, fill algorithms, tests, and UI renderers. Added FillSpiral with center remnant detection and recursive FillBest on the gap between the 4 spiral quadrants. RectFill.FillBest now compares spiral+center vs full best-fit fairly. BestCombination returns a CombinationResult record instead of out params. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
