  "input": {
    "prompt": " Photo on a London street (recognizable but not overly specific—generic Westminster vibes): two people in business attire exchange a firm handshake while banknotes and coins in their other hands appear useless—either crumpled, fading, or sitting in an open wallet like props. A small government-style poster on a nearby lamppost reads “APRIL 20: CURRENCY TEMPORARILY SYMBOLIC. PLEASE USE VIBES.” Natural daylight, documentary feel.  "
