-## Fix Handwriting Border Color Inconsistency
-
-### Phase 0: Code Quality Fix
-
-#### Task 0.1: Remove Duplicate `.notebook-panel::before` Definition ✅
-- [x] Identify duplicate `.notebook-panel::before` definitions (lines 459-469 and 471-482)
-- [x] Remove one duplicate definition
-- [x] Ensure remaining definition has all necessary properties
-- [x] Verify paper texture still works correctly
-- **File**: `app/globals.css` (around lines 458-482)
-- **Priority**: Low (doesn't affect border colors, but improves code quality)

-### Phase 1: Fix Card and Panel Borders
-
-#### Task 1.1: Fix `.notebook-panel::after` ✅
-- [x] Remove `background-image` declarations that use SVG patterns (lines 427-434)
-- [x] Keep `background-color: rgb(var(--notebook-divider))` (line 426)
-- [x] Keep gradient masks for border shape (lines 436-453) - these define the 2px border area
-- [x] Add SVG pattern masks to `mask-image` (combine with existing gradient masks)
-- [x] Update `mask-composite` to combine gradient masks + SVG pattern masks
-- [x] Verify border appears as consistent grey color with handwriting texture
-- **File**: `app/globals.css` (around line 418-456)
-- **Note**: Must combine gradient masks (border shape) + SVG pattern masks (texture) in single `mask-image` declaration

-### Phase 4: Verify and Test
-
-#### Task 4.1: Visual Testing
-- [ ] Test borders in light mode - should be light grey (`#E5E0D6`)
-- [ ] Test borders in dark mode - should be medium grey (`#6B7280`)
-- [ ] Verify no black color appears in borders
-- [ ] Check all card borders (notebook-panel, loose-leaf-card)

-#### Task 4.3: Code Review
-- [ ] Ensure no `background-image` uses SVG pattern variables
-- [ ] Ensure all borders use `mask-image` with SVG patterns
-- [ ] Ensure all borders use `background-color: rgb(var(--notebook-divider))`
-- [ ] Verify theme switching works correctly
-
-**Verification Criteria:**
-- All borders display in consistent grey color (no black)
-- Borders respect theme colors (light grey in light mode, medium grey in dark mode)
-- Handwriting pattern shape is preserved (wavy lines)
-- No visual regressions in border appearance
-- All border implementations follow the same pattern
