🛡 SAP Sheets

Each product is a box representing the vest. Add Big or Small SAPs, pick their location (front, rear, side, neck… or your own), then drag the plates around the box to match the real arrangement. Set the sew-on code, and flag any panel that's cut but gets no label (🏷 → 🚫). The big/small totals sync to the catalogue automatically, so serials and the labels page know exactly how many SAP labels each vest, carrier or demining item needs. The ballistic recipe (material / layers / stitching) lives in Ballistic Recipes — it's multiplied against these panel quantities to work out material usage. (This replaces the old “SAP & Label Panels” page.)
