Hello world

# 1. Generate an owner key and a session key.
and keygen --out owner.key
and keygen --out session.key

# 2. Write the mandate (owner-signed CreatePolicy).
and policy mint \
  --owner owner.key \
  --account-id 22 \
  --policy-id 42 \
  --grantee-hex "$(and public-key session.key)" \
  --max-volume-per-day-usdc 50000 \
  --max-drawdown-pct 1500

# 3. Run.
and order place \
  --session session.key \
  --account-id 22 --policy-id 42 \
  --market-id 7 --client-order-id 1 \
  --side bid --quantity-lots 5 --price-ticks 103

The session key cannot exceed the mandate. The protocol refuses any intent that would.
