### **Phase 8: Storage Monitoring**
### **Phase 8: Storage Monitoring** ✅ **COMPLETE**
**Goal**: Show storage usage and limits
- [ ] Calculate total localStorage usage
- [ ] Display as progress bar or text (e.g., "2.3 MB / ~5 MB")
- [ ] Show individual snippet sizes in list
- [ ] Add warning indicator when approaching 80% capacity
- [ ] Display draft vs published size differences
**Deliverable**: User can see storage consumption
**Deliverables**:
- Storage usage calculation using Blob API for accurate byte counting
- Progress bar display showing usage vs 5MB limit (e.g., "2.3 MB / 5 MB")
- Visual warning states: green (normal), orange (90%+ warning), red (95%+ critical)
- Storage monitor positioned at bottom of snippet panel below metadata
- Automatic updates after every save operation
- Alert dialog when localStorage quota is exceeded
- Flexbox layout ensuring monitor stays at panel bottom with scrollable snippet list
