研究方向
Investigate the zlib error by creating a minimal reproduction with many async image writes. Focus on the call stack in pngjs's sync inflate.js and parser sync.js. Determine if the error is due to concurrent writes or incomplete data. Check if the issue is related to the async nature of the code in the pastebin.
