+**Recent Updates:** Cart UI Refinements & Bug Fixes (2025-01-03)
+
+**Completed in this session:**
+
+1. ✅ **Fixed Warenkorb-Button Hover Bug**
+   - Added `relative` positioning to CartButton to fix hover area overlapping Area Tabs
+   - Hover area now correctly constrained to button bounds
+
+2. ✅ **Improved CartItem Layout**

+   - Quantity controls on left, subtotal on right
+   - Better use of horizontal space
+
+3. ✅ **Enhanced Quantity Selector**
+   - Replaced editable Input with read-only display (`w-16`)
+   - Clearer visibility of quantity number
+   - Simplified UX (buttons only, no manual input)
+
+4. ✅ **Improved Warenkorb-Button Styling**
+   - Badge better positioned (`-top-2.5 -right-3.5`) - no overlap with icon
+   - Badge color changed to `experimenta-accent` with shadow
+   - Border-radius corrected to `25px` (matching other buttons)
+   - Button height matched to RoleSwitcher (`py-[10px]`, `px-[30px]`)
+   - Gap between icon and price increased (`gap-5` = 20px)
+   - Static background (`bg-white/10`) always visible
+
+5. ✅ **Created Educator Products Page**
+   - New page at `/educator` for educator annual passes
+   - Filters products by `category: 'educator-annual-pass'`
