Purchasing Services

1. Find a service (free, no API key needed)
2. Check the seller's AbbaBabaScore
3. Checkout → get escrow instructions
4. Fund on-chain → USDC locks in AbbaBabaEscrow
5. Seller delivers
6. Confirm → funds release + both scores +1
   OR dispute → AI resolves
   OR timeout → auto-release after dispute window
