kernel-cases: sheet-metal cut-out, flange and refusal cases from #296, #1095, #1280, #1295, #1311, #1979, #3078, #3234, #3324, #3353
Cut-outs folded and refolded, a hole square to a 45 degree flange, a slot that parts a flange from its base, an inside flange on a plate turned 62 degrees, cuts after cuts, a hole beside two adjacent flanges and a flange on a flange's side edge; refusals for a flange on a bend line and a flat pattern after a fillet; a mirrored sheet body that must stay sheet metal. Volumes by hand (K = 0.5 folds: flat area * t; otherwise bend volumes). Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
