Functions
float	pulsatrix::NormalizeUnsigned (float value, float max_abs)
	Normalizes value into [0, 1] against a known maximum magnitude, for unsigned (magnitude-only) quantities such as saliency intensity or ablation effect.
float	pulsatrix::NormalizeSigned (float value, float max_abs)
	Normalizes value into [-1, 1] against a known maximum absolute magnitude, for signed quantities such as attribution direction (positive/negative contribution).
RgbColor	pulsatrix::ViridisColormap (float normalized_value)
	Viridis colormap – perceptually uniform, colorblind-safe – for sequential/unsigned magnitude (hc_information_visualization.md SS4: "Recommended Color Systems").
RgbColor	pulsatrix::DivergingColormap (float signed_normalized_value)
	Blue-White-Red diverging colormap for signed attribution (positive/negative contribution) – hue encodes direction only, never magnitude (hc_information_visualization.md SS1's Cleveland-McGill rule: color hue is categorical/directional, magnitude must be position or length).
