CssKeywordLinearTransform class
Bounds-aware CSS keyword transform for linear gradients.
CSS corner directions such as to-br depend on the paint rectangle's aspect
ratio. Flutter's GradientRotation is bounds-independent, so this transform
preserves CSS keyword behavior for utilities and schema round-trips that
need that parity.
