const BUDGET_FAQS = [
  { q: "How much should I budget for a two-week international trip?", a: "Floor: ~$2,500 for SE Asia or Eastern Europe (excl. flight) at the budget tier. Mid: ~$4,500 for Western Europe, Japan, or Australia. High: ~$8,000+ for Iceland, Switzerland, or Scandinavia. Add $700–$1,400 for the international flight on top. The right total is the per-diem of your destination tier × 14 + flight + 10% buffer for hidden costs." },
  { q: "What's the cheapest way to handle currency abroad?", a: "Two-card stack: a 0%-FX credit card for everything you can pay by card (Capital One Venture, Chase Sapphire, Schwab Investor Checking has no ATM fees), and a debit card for ATM withdrawals on the local currency. Skip airport currency kiosks (8–12% spread) and your home bank's currency order desk (3–5% spread). Pull cash from a bank ATM on arrival for under 1%." },
  { q: "Should I use a debit card or credit card abroad?", a: "Credit card at the register, debit card at the ATM. Debit at the register is a fraud risk — if it's stolen, your bank account empties before you notice. Credit is also where the FX-fee waivers and travel insurance live. Use debit only at bank-branded ATMs (not standalone kiosks) for cash, and only as much cash as you'll spend in 4–5 days." },
  { q: "How much cash should I actually carry?", a: "Cash for 4–5 days of cash-only spending — markets, taxis, tips. For most destinations that's $80–$200 USD-equivalent. Carry the rest on cards. Refill at bank ATMs. Keep $50 USD in a separate pocket as emergency-exit cash. Don't carry the whole trip's cash — pickpocket math is brutal." },
  { q: "What's a realistic daily food budget?", a: "Budget tier: $15–$28/day means street food, market lunch, one cheap dinner. Mid tier: $35–$60/day is two sit-downs and a coffee. High tier: $70–$120/day is three sit-downs with one tasting-menu night per week. Western Europe and Japan run high on the food line because casual restaurants are still $20+ per entrée — adjust." },
  { q: "How do I avoid getting destroyed by hidden fees?", a: "Pre-trip: read the airline's baggage policy, buy your eSIM at home, check visa requirements at 90 days out. On arrival: get cash from a bank ATM (not airport kiosk), set up local transit cards (Suica, Octopus, Oyster — all rechargeable). Tipping: research the country's culture before you sit down at the first restaurant. The 8% hidden-cost line item is what makes budgets fail." },
  { q: "Is travel insurance actually worth it?", a: "For international trips: yes, always. Standard tier ($30–$80) covers trip cancellation. Add medical & evacuation ($50–$120) — evacuation alone runs $25k–$100k if something goes wrong. The premium is 5–10% of trip cost; the coverage is 100x that. CFAR is the upgrade that lets you cancel for any reason and recover ~75%, but it must be purchased within 14–21 days of first booking." },
  { q: "How do I track spending without making the trip about spending?", a: "5 minutes a night, before bed. Open a notes app or a spreadsheet, log the day's amount by category — bed, food, transit, activities, other. That's it. Don't reconcile mid-trip. Don't optimize while you're there. The point is one number per category at the end of the day, so when you reconcile within 14 days of getting home, you actually have the data." },
