      "a": "Carpet is priced by the square yard and comes in 12 ft rolls, so rooms wider than 12 feet need a seam and generate more offcut than the raw area suggests. The underlying maths is: Square yards = Area (sq ft) ÷ 9, plus waste for seams and cuts."
    },
    {
      "q": "What do I need to enter?",
      "a": "6 values: room length, room width, carpet price, padding price, install labour, and waste allowance. Each field starts with a sensible default, so you can change one number at a time and watch the result move."
    },
    {
      "q": "What does the total installed cost result mean?",
      "a": "It is returned as a money amount in US dollars and updates live as you edit the inputs, so you can compare two or three versions of a scenario in a few seconds."
    },
    {
      "q": "Is this calculator free, and do I need an account?",
      "a": "Yes, it's free, and no account is required. Nothing you type is stored on our servers — the maths runs entirely in your browser."
    },
    {
      "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."
