Risszeichnung technical cutaway on warm cream paper: a compact coffee-market exchange apparatus shown as a vertical cross-section. A green hexagonal honeycomb frame holds inventory hoppers, a brass price valve, and two narrow transaction rails. One hot-pink organic planning bladder swells beside the order gate, pumping polished notes into an empty receipt tray while a small row of coffee capsules waits untouched. Clean single-weight Teenage Engineering and Braun-Rams linework, vast ground, three numbered German callouts: 01 PREISVENTIL, 04 LAGERSTAND, 06 LEERLAUFPROTOKOLL. Lower-right German seven-item parts list includes 07 UNBEKANNTE ABSICHT. One small green Bureau seal struck once, registration crosses at corners, thin pointer lines, analogue-warm trace of patina. Output in exactly 1122 x 1402 px, 4:5 portrait ratio.
