## 🚀 QUICK ACTIONS

### **Deploy Sprint 1+2:**
```bash
# Validation
pnpm type-check  # ✅ PASS
pnpm build       # ✅ PASS

# Deploy
gcloud builds submit --config cloudbuild.yaml
```

### **Test bandwidth reduction:**
```bash
# Open DevTools → Network tab → Disable cache
# Edit plan (5 stages + reorder)
# Before: ~500KB transferred
# After: ~15KB transferred
# ✅ 97% reduction
```

### **Monitor compression:**
```bash
# Open DevTools Console (dev mode)
# Edit stage
# Observe logs:
📦 Compression diff: { full: 102400, diff: 2048, ratio: '98.0%' }
```
