- New MathExpressionParser: ~150-line recursive-descent evaluator for + - * / and parens; strict whitelist, no ScriptEngine
- New ExpressionAwareTextFieldFormatter: subclass of TextFieldUnitFormatter that runs the parser before falling back to super
- TransformationSettingsPanel: X, Y, Width, Height, Rotation fields now build via createExpressionField helper using the new formatter
- Tests: 38 unit + 5 integration cases covering grammar edges, unit/percent rounding, and field-wiring regression guard
