🎓 Key Learnings & Patterns

Pattern 1: Separation of Concerns

Data Logic (Hooks)
  ↓
State Management (React + Database)
  ↓
UI Rendering (Components)

Pattern 2: Configuration as Data

Hardcoded → Database/JSON
Colors     → config.statusColors
Columns    → config.columnDefinitions
Tabs       → config.tabs
Icons      → config.iconMap

Pattern 3: Reusable Logic

Component-specific → Hooks → Lua Scripts
Private state      → Custom hooks
Shared data        → Database
Complex logic      → Lua (runtime-modifiable)

---

🚀 Next Steps

1. Review this strategy with stakeholders
2. Approve database schema changes
3. Assign team members to violations
4. Schedule weekly sync meetings
5. Create GitHub issues from checklist
6. Start Phase 1 implementation
