+USDT account rebalancing is a manual action, not an automatic post-close side effect. The inline `账户再平衡` action becomes available only after the account-order widget has continuously reported zero positions and zero open orders for two seconds, and a fresh all-symbol futures-position response also confirms that every position is flat. Starting any script trade or cancel task invalidates that eligibility immediately. When a cancellation task ends, readable zero account counters restart the same guarded eligibility window even if the counts did not change during the task. The action opens a script-owned native `<dialog>` styled with Binance color variables; it shows current and target balances plus the exact transfer plan, focuses Cancel by default, and proceeds only after an explicit confirmation. Escape and Cancel close it without transferring funds.
 
 The rebalance path is pinned to the current Binance page bundle contract instead of automating the native transfer dialog. It reads Spot and Funding available USDT from `/bapi/asset/v2/private/asset-service/wallet/balance`, reads the U-M Futures transferable amount from `/bapi/futures/v1/private/future/user-data/getMaxWithdrawAmount`, and submits at most two sequential transfers through `/bapi/asset/v1/private/asset-service/wallet/transfer` with `{ asset, amount, kindType }`. Wallet rows are identified by the stable `accountType` values `MAIN`, `CARD`, and `FUTURE`; `walletName` is localized and must not be used as an identifier. The private transfer BAPI uses those same account codes; do not substitute the public SAPI names `FUNDING` or `UMFUTURE`. It does not save an API key and does not fall back to DOM clicking if this private BAPI contract changes.
