...
Performance improvements:
- Vite build: manual chunks, terser minification, optimizeDeps
- API response caching with 5s TTL via axios interceptors
- React.memo for SidebarMenuItem, useCallback for handlers
- CSS classes replacing inline styles to reduce reflows
UI/UX enhancements (inspired by SAP Fiori, Linear, Feishu):
- Dashboard: trend indicators, sparkline charts, CountUp animation on stat cards
- Dashboard: pending tasks section with priority labels
- Dashboard: recent activity timeline
- Design system tokens: trend colors, line-height, dark mode refinements
- Enhanced quick actions with hover animations
Accessibility (Lighthouse 100/100):
- Skip-to-content link, ARIA landmarks, heading hierarchy
- prefers-reduced-motion support, focus-visible states
