      "a": "7 values: batch size, grain / extract cost, hops cost, yeast cost, propane, caps, sanitizer, trub & packaging loss, and taproom pint price. Each field starts with a sensible default, so you can change one number at a time and watch the result move."

    {
      "q": "How accurate is the result?",
      "a": "It applies the standard formula exactly, so the arithmetic is precise. Estimates assume standard, average conditions — local rules, pricing, and materials vary."

      "q": "Who is this tool for?",
      "a": "It's built for anyone doing everyday planning maths — a quick estimate that would otherwise need four browser tabs and a calculator app."
