## 🎓 KEY TECHNICAL DECISIONS

### Architecture
1. **Composition API**: Using `<script setup>` for all components
2. **Pinia Setup Stores**: Composition API style for state management
3. **Type Safety**: Strict TypeScript with explicit types
4. **Middleware Pattern**: Route-based authentication guards
5. **Layout System**: Separate layouts for app vs game views

### State Management
1. **Store Separation**: Auth, Game, UI stores for clear boundaries
2. **localStorage Persistence**: Auth state survives page reloads
3. **Computed Properties**: Efficient reactive derived state
4. **No Vuex**: Pinia is more modern and type-safe

### Styling
1. **Tailwind CSS**: Utility-first approach for rapid development
2. **Mobile-First**: All layouts start with mobile breakpoints
3. **Custom Theme**: SBA brand colors in tailwind.config
4. **Minimal Custom CSS**: Leverage Tailwind utilities

---

## 🔧 KNOWN ISSUES & FUTURE WORK

### Minor Issues (Non-Blocking)
1. Composable tests need mocking improvements (54 tests)
2. Error pages not created (404, 500) - defer to Phase F8
3. Loading skeleton screens - defer to Phase F8
4. Toast component not yet created - Phase F2
5. Modal component not yet created - Phase F3

### Future Enhancements (Post-MVP)
1. PWA support (service workers, offline mode)
2. Push notifications
3. Dark mode toggle
4. Accessibility audit and improvements
5. Animation polish (framer-motion or GSAP)
