    question: "What is 8bitcn?",
    answer:
      "A retro-styled component library for React. Think shadcn/ui but everything looks like it came from a 1985 arcade cabinet.",
  },
  {
    category: "General",
    question: "Is this production ready?",
    answer:
      "Yes. Every component is accessible, responsive, and tested. The pixel borders are decorative — the engineering is serious.",
  },
  {
    category: "Setup",
    question: "How do I install components?",
    answer:
      "Use the shadcn CLI: pnpm dlx shadcn@latest add @8bitcn/button. Components are copied into your project — no runtime dependency.",
  },
  {
    category: "Setup",
    question: "Does it work with existing shadcn?",
    answer:
      "Absolutely. 8bitcn wraps shadcn components. Your existing setup stays intact. Just add the retro layer on top.",
  },
  {
    category: "Billing",
    question: "Is the library free?",
    answer:
      "The core library is MIT licensed and free forever. Premium blocks and templates will be available separately.",
  },
  {
    category: "Billing",
    question: "Do you offer team licenses?",
    answer:
      "Not yet, but it's on the roadmap. For now, one purchase covers your entire team since components are copy-pasted.",
  },
