Wet Lab silver-gelatin still, vertical close view: a battered black card cabinet lies open on a steel specimen tray in a near-black institute room. 01 intake chute releases damp paper slips, 02 graphite backlink tendrils stitch them to labelled drawers, and 03 master-key aperture is held gently by one gloved human hand. A concentrated signal-cyan graph filament glows behind the cabinet glass. Real hex lattice mesh forms the tray base; a blue plastic label maker sits beside folded gauze, quietly ridiculous. Hard warm chiaroscuro, copper fittings, sparse German callouts, Bureau seal struck once on the tray rim, no filing label. Output in exactly 1122 x 1402 px, 4:5 portrait ratio.
