 * Validity window for a submitted Soroban invocation (seconds).

 * This becomes the transaction's `maxTime`. Validators reject a tx whose
 * `maxTime` has passed (`txTOO_LATE`), so the window must outlast the slowest
 * realistic sign-then-submit path: hardware wallets, careful manual review,
 * and institutional approval flows (e.g. Fordefi) that don't sign instantly.
 * 10 minutes comfortably covers those while staying well inside the Soroban
 * footprint/ledger-entry TTL, so the simulated footprint can't go stale first.
 *
 * The window is anchored to the *network* clock (see `getNetworkCloseTime` in
 * soroban.ts), not the signer's `Date.now()`, so a skewed device clock can't
 * make the deadline expire early.
