 * @title ICrossChainFlashBridge

 * @dev Wire to `UniversalCCIPFlashBridgeAdapter` (→ `UniversalCCIPBridge.bridge`), a dedicated adapter, or a mock in tests.
 *      Implementations MUST pull from `msg.sender` (e.g. `transferFrom`) up to `amount` after allowance.
 *      For `UniversalCCIPFlashBridgeAdapter`, optional `extraData` encodes
 *      `(bytes32 assetType, bool usePMM, bool useVault, bytes complianceProof, bytes vaultInstructions)`; empty uses zeros/false.
