    "prompt": " Illustration: a personified decimal point character in Victorian attire (top hat, tiny cane, monocle) standing beside a bank transfer screen. The UI shows a small refund amount being rounded up to “£10,000” with a tooltip reading “out of politeness.” Include a fintech office background and engineers in debate—one holding a “Fix now” sign, another holding a “Kind of charming?” sign. Ensure the pound symbol and amount are clear."
