Research direction
Reproduce the crash at the provided app URL using the recorded swap state, then inspect the stack trace entries in the deployed static JavaScript chunks, especially the call through fromFractionalAmount and divide. Done means this zero-valued input no longer crashes the swap interface; the payload names no source files or tests to run.
