    "prompt": " Photo-style illustration of an official-looking press podium in London with a banner “Royal Society of Making Stuff Up Late,” where a spokesperson unveils a giant foam letter “ä” on an easel like a product launch. In the foreground, confused reporters hold notebooks showing “Thänk you,” “Cän’t,” and “Plän,” while a teacher in the back clutches a surprise test paper titled “You Should Have Known This.” Include subtle British civic details (stone building, Union Jack pin, rain-specked window) without using any real institution logos.
