## ✅ Correct Implementation (41 items total):

- ✅ All 13 stat cards now have proper period comparisons
- ✅ All tables are correctly filtered by period
- ✅ Global/store-level data correctly excluded from period filtering
- ✅ All primary metrics have proper comparisons
- ✅ Stock data remains global (correct)
- ✅ Customer segments (VIP/At Risk) remain global (correct)
- ✅ "All Time" period correctly shows no comparison (undefined)
- ✅ Build successful with no errors

## 🎯 Comparison Logic Implemented:

**For period-based data (7/14/30 days):**
- Current period data vs. previous period data
- Example: 7 days compares last 7 days vs. previous 7 days
- Percentage change calculated and displayed with trend indicator

**For "All Time" period:**
- No comparison shown (change = undefined)
- StatCard component handles undefined gracefully
- No "vs previous period" text displayed

---

**Status:** ✅ COMPLETE - All dashboard stat cards now have consistent comparison logic!
