Wet Lab, a silver-gelatin colour close-up of a black research-routing organ on a cream steel tray, 4:5 portrait. One phosphor-green citation capsule enters through a translucent membrane and branches into pale evidence tubes; a gloved hand isolates the first contaminated junction with forceps. A real hexagonal honeycomb lattice supports the tray insert. Filing-layer callouts label 01 source intake, 02 provenance branch, 03 verification clamp. An ordinary bent paperclip sits beside the specimen as if it has been promoted to a diagnostic instrument. Hard warm key light, deep near-black shadow, circular Bureau seal struck once. No faces, German or illegible in-image lettering. Output in exactly 1122 x 1402 px, 4:5 portrait ratio.
