🧠 Analysis: Refactor vs Rewrite Strategy for App Frontend React

### Description

Summary

We're conducting a structured analysis to determine whether the current application should undergo a refactor or a complete rewrite based on architectural complexity, performance, and long-term maintainability.

### In scope

Checkpoints

- Identify critical architectural bottlenecks
- Map current vs desired performance/scalability characteristics
- Review refactoring attempts and migration blockers
- Conduct team-wide survey with scoring model (maybe)
- Review previous rewrite proposals (if any)
- Draft an ADR for recommendation
- Present findings to technical leadership for alignment

Output

✅ Recommendation (Refactor / Rewrite)
