+Button text: text-sm (14px) font-medium
+Body text: text-sm (14px)
+Small text: text-xs (12px)
+```
+
+### Spacing System
+```css
+/* Consistent spacing */
+Container padding: p-4 (16px)
+Item gaps: gap-3 (12px)
+Section gaps: gap-4 (16px)
+Button padding: px-3 py-2 (12px 8px)
+```
+
+### Color Palette (WCAG AA Compliant)
+```css
+Primary: #3B82F6 (Blue-600)
+Success: #10B981 (Green-500)
+Warning: #F59E0B (Amber-500)
+Error: #EF4444 (Red-500)

+- CSS custom properties
+- No IE11 support required
+
+## Known Limitations
+- Chart animations disabled for reduced-motion users
+- Some features require JavaScript enabled
+- Optimal experience on viewports ≥ 320px wide
+
+## Future Enhancements
+- Add chart export functionality
+- Implement advanced filtering
+- Add data range selector
