# Phase 5: DashboardView.vue - Major Refactoring 🚀

**Priority:** 🔥 CRITICAL - Biggest impact
**Duration:** 24-32 hours
**Status:** ⏸️ Not Started

---

## Obiective

1. **Reduce 2,010 lines → 300 lines** - 85% reduction (1,710 lines eliminated)
2. **Replace custom CSS with global patterns** - Use Phase 2-4 work
3. **Consolidate responsive breakpoints** - 4 breakpoints → 1
