  "input": {
    "prompt": " Poster-style illustration mimicking public-information design: bold heading “DON’T PANIC (UNLESS YOU WANT TO)” and a simple step-by-step diagram—1) see message containing box characters, 2) back away, 3) clear cache, 4) reassure device it is loved; include a tiny sample like “┬┬:├KE=<<” in a warning triangle; colours like muted government pamphlet palette; no real agency logos, but convincingly official layout."
