  "summary": "A sealed spot-the-true-definition game: for each obscure word the AI forges two fakes and hides the real meaning, committed before you play so it can't cheat.",
  "tagline": "Seven real but little-known words, each with three definitions — one true, two forged by the AI. The true meanings are sealed with a SHA-256 hash before you start, so the AI cannot move the answer to catch you.",

  "faq": [
    {
      "q": "How do you stop the AI from changing which definition is right?",
      "a": "The seven true definitions and which lettered slot each sits in are written before you play and locked with a SHA-256 hash printed on the card. The AI reads the definitions only from that fixed script and cannot move the true answer once you commit to a letter. You can hash the revealed script yourself to confirm nothing changed."
    },
    {
      "q": "What makes it different from a trivia quiz?",
      "a": "The two wrong definitions are not random — they are deliberate forgeries built to sound as plausible as the real one, borrowing real-looking roots and histories. It is a game of spotting the counterfeit, so etymology helps only up to a point."
    },
    {
      "q": "Are the words and definitions real?",
      "a": "Yes. Every headword is a genuine, dictionary-attested English word, and the true definition is its real meaning. Only the two decoys per card are invented. At the end the AI reveals all seven words and what they actually mean."
    },
    {
      "q": "Do I need an account or any tools?",
      "a": "No account beyond the chat app. Paste the card into ChatGPT, Claude, or Gemini to begin. Verifying the seal uses any SHA-256 tool, including ones built into your operating system, and a save code lets you pause and resume."
