- tokens/colors.ts: backgrounds, surfaces, text, pigments, semantic, glass, shadows, light theme
- tokens/typography.ts: font families, sizes, weights, line heights, letter spacings
- tokens/spacing.ts: spacing scale, radius, z-index, layout
- tokens/motion.ts: durations and easing functions
TASK-DS-003: Added missing Storybook stories
- EmptyState.stories.tsx (8 variants: default, icon, action, search, sizes, card, centered)
- ButtonLoading.stories.tsx (6 variants: default, loading, text, destructive, outline, small)
- ContentFadeIn.stories.tsx (2 variants: default, card)
- DesignTokens.stories.tsx (visual token reference: pigments, backgrounds, text, typography, spacing, radius)
