- Introduced exact arithmetic with support for large integers and fractions in `exact.gd`, `big_integer.gd`, and `exact_value.gd`.
- Implemented a comprehensive test suite in `test_exact_math.gd` to validate arithmetic operations against expected results.
- Added a README in `math` directory to document the exact arithmetic system and its usage.
- Ensured that all arithmetic operations maintain precision without floating-point errors, using a custom representation for large numbers.
- Included methods for encoding and decoding exact values for serialization.
- Implemented a new test script `test_action_values.gd` to verify the precision of fractional action amounts and the distinctiveness of adjacent values.
- Added checks to ensure that action values are correctly formatted and that the distribution of actions preserves distinct requests.
- Included validation for rendered button labels to confirm they are distinguishable.
