研究方向
Investigate the DataCloneError thrown when loading the wasm bundle in Safari. Check the WebAssembly instantiation code in the playground (likely in a file like src/playground.js or similar). The error suggests that some data (likely a wasm module or response) cannot be cloned via structured clone algorithm. Look into whether the issue is related to SharedArrayBuffer or cross origin isolation, as Safari has stricter requirements. Also check for any recent changes to the loading logic. Refer to related issue #528 and comments for additional context.
