Failed to initialize WASM, using fallback

Error message

Failed to initialize WASM, using fallback

Log warning in initialize: locating or loading the economy WASM module failed, so the bridge marks itself initialized anyway and runs the pure-JavaScript implementation of the economic calculations.

Solutions

1. Check the WASM module load error; the JS fallback preserves correctness at lower speed, so rebuild or reinstall the WASM package to restore performance.
