Dedicated large inspection art for graphics cards

192x128 drawings made for the magnifier tray instead of enlarging the
48x32 item sprite: nine-blade fans, fin stack, heat pipes, power connector,
PCB parts, per-contact gold fingers; back with brushed backplate, QR and
barcode sticker, seal. Appearance overlays share coordinates with the base.
