Research direction

Look at the existing money mask directive in the repository (likely in src/money mask.js or similar). Identify how positive numbers are currently handled and where validation occurs. Modify the regex or input handling to allow an optional leading minus sign. Ensure negative numbers are properly displayed and parsed. Test with various negative inputs and edge cases (e.g., 0, decimals). Consider any existing tests to extend.
