Quantitative hue-based grouping, perceptual similarity metrics, and usage analysis
Colors quantitatively grouped by OKLCH hue angle. Neutrals have chroma < 0.015.
Perceptual distance (ΔE) calculated using OKLCH. Lower = more similar. Pairs with ΔE < 0.05 are consolidation candidates.
Class usage counts from packages/kumo/src/**/*.tsx (bg-, border-, ring-, fill-, outline-, shadow-, divide-, from-, via-, to-)
