const faqs = [
  {
    q: "What types of cards can Echo scan?",
    a: "Echo works with any printed or handwritten response card, guest card, prayer request form, connection card, or decision card. If a human can read it, Echo can too. We support PDF (including multi-page duplex scans), JPEG, PNG, and WebP formats.",
  },
  {
    q: "How accurate is the AI OCR?",
    a: "Echo uses the same vision AI models that power leading enterprise document processing. For printed text, accuracy is near-perfect. For handwriting, accuracy typically ranges from 85-95% depending on legibility — which is why every card goes through a human review step before syncing.",
  },
  {
    q: "Do I need special scanning equipment?",
    a: "No. Any office scanner, multi-function printer, or even a smartphone camera works. If your scanner supports 'Scan to Email' or 'Scan to FTP' (most do), you can automate the entire process with zero manual uploading.",
  },
  {
    q: "How does the Planning Center integration work?",
    a: "Echo connects via OAuth to your Planning Center People account. When a card is processed, it matches the person by email or name. If they exist, it updates their record. If not, it creates a new person. You can also add them to specific lists automatically.",
  },
  {
    q: "Is our congregation's data secure?",
    a: "Yes. All data is encrypted in transit and at rest. We use role-based access controls, invitation-only team access, and email verification. Your data is stored on enterprise-grade infrastructure (Supabase + Vercel) with SOC 2 compliance.",
  },
  {
    q: "Can we self-host Echo?",
    a: "Enterprise plans include the option for on-premise deployment via Docker. This is ideal for denominations or large organizations with strict data residency requirements.",
  },
  {
    q: "What happens if we go over our card limit?",
    a: "We'll never cut you off mid-month. Overage is billed at $0.08 per card. If you're consistently exceeding your plan, we'll suggest upgrading to save money.",
  },
  {
    q: "Is there a contract or commitment?",
    a: "No. Monthly plans can be cancelled anytime. Annual plans are paid upfront for the discount but you can switch to monthly at renewal. The free tier is free forever.",
  },
