Polymarket Combo Builder

Build an atomic Polymarket combo (parlay) - pick 2+ binary market legs, get live combined odds quoted over RFQ, and place the whole thing as ONE signed order. Every leg must hit to win; any single leg losing is a total loss of the stake. Live placement works with EOA / self-custody wallets today; deposit-wallet live is blocked pending Polymarket. Dry-run by default (a local plan, not a paper fill). Sports-general (World Cup ready).
