Production separations — Artwork, HPI-White and CutContour were supplied as discrete registered plates; the barcode remained readable and scan-verified.Layer architecture — The 73.66 mm pouch resolves into a registered Yupo body, depression tray, loose patch and tamper-evident lid assembly.Print iteration — Four supplier rounds corrected cut drift, white-underbase loss and foil-channel behaviour into the final production handoff.Functional prototype — The opened hand-built unit exposes both inner faces and the real VOID ghost, proving the peel and residue-transfer event at studio-prototype fidelity.
