NestProgress gains PreviewSheet, a detached plate for the stock the preview parts lie on; Irregular builds one per stock. PlateView draws it (size, edge spacing, clamps) in place of the plate while the preview is shown and drops it whenever the preview is cleared or the plate changes. Auto Nest zooms out when a trial sheet falls outside what it has already shown. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
