🔍 Key Highlights

✨ Design System Strengths

1. Fully typed TypeScript — strong IDE support
2. Semantic HTML — accessibility-first
3. Dark/light theme — CSS variables, not hardcoded
4. Responsive by default — mobile-first
5. Consistent patterns — explicit props, no prop spreading
6. Theme-aware charts — HSL variables for dynamic theming
7. Mapbox fallbacks — graceful degradation

⚙️ Integration Ready

1. All components exported — central index.ts barrel export
2. Query keys cached — React Query factory pattern
3. API fully documented — TypeScript interfaces
4. No external deps — uses only Recharts + Mapbox (already included)
5. CSS vars integrated — Tailwind + globals.css

📋 Missing Pieces (For Homepage Refactor)

1. TEC-3030 design spec — check project management
2. Homepage layout — design system is for dashboards
3. Marketing copy — component docs only
4. Backend endpoints — mock data shown in AgentPerformance
