+# Semantic Styling Framework Refactoring Checklist
+
+This document tracks the refactoring of our CSS and TSX files to use the semantic styling framework, eliminating duplicate CSS and creating consistent component patterns.
+
+## Framework Overview
+
+Our semantic styling framework consists of:
+- **`colors.css`** - CSS variables and color system
+- **`semantic-components.css`** - Semantic component classes (cards, badges, actions, drag-and-drop, etc.)
+- **`application.css`** - Utility classes and base component styles
+- **`aspectRatios.css`** - Dedicated aspect ratio styling for slides (preserved)
+
+## Refactoring Principles
+
+1. **Use semantic classes** instead of component-specific CSS
+2. **Leverage CSS variables** for colors, spacing, and typography
+3. **Eliminate duplicate styles** by consolidating common patterns
+4. **Preserve presentation/theme CSS** - slides should NOT use semantic framework
+5. **Only keep minimal component-specific CSS** when absolutely necessary
+
+---
+
+## ✅ COMPLETED REFACTORING
+
+### Core Framework Files
+- **`src/styles/colors.css`** ✅ - Comprehensive CSS variable system
+- **`src/styles/semantic-components.css`** ✅ - Semantic component classes
+- **`src/styles/application.css`** ✅ - Utility classes and base styles
+- **`src/styles/aspectRatios.css`** ✅ - Preserved dedicated slide aspect ratios
+
+### Presentation Components
+- **`src/components/presentations/PresentationEditor.tsx`** ✅ - Uses semantic classes
+- **`src/components/presentations/PresentationEditor.css`** ✅ - Reduced by ~85%, only layout-specific CSS
+- **`src/components/presentations/SlidesSidebar.tsx`** ✅ - Uses semantic classes
+- **`src/components/presentations/SlidesSidebar.css`** ✅ - Minimal component-specific CSS
+- **`src/components/presentations/shared/SlideThumbnail.tsx`** ✅ - Uses semantic classes
+- **`src/components/presentations/shared/SlideThumbnail.css`** ✅ - Minimal component overrides
+- **`src/components/presentations/PresentationMode.tsx`** ✅ - Uses semantic classes for UI
+- **`src/components/presentations/PresentationMode.css`** ✅ - Isolated slide content from semantic framework
+- **`src/components/presentations/shared/LoadingState.tsx`** ✅ - Uses semantic classes
+- **`src/components/presentations/shared/LoadingState.css`** ✅ - Minimal overrides
+- **`src/components/presentations/shared/ErrorState.tsx`** ✅ - Uses semantic classes (slide-editor version)

+- **Needs**: Use semantic form classes
+- **Likely Issues**: Custom form styling
+
+#### **`src/components/presentations/PresentationDetailsForm.css`**
+- **Status**: Not examined/refactored
+- **Needs**: Use `.form-group`, `.form-input`, `.form-label` semantic classes
+- **Likely Issues**: Duplicate form styles
+
+#### **`src/components/presentations/AspectRatioSelector.tsx`**
+- **Status**: Not examined/refactored
+- **Needs**: Use semantic card and selection classes
+- **Likely Issues**: Custom card selection UI
+
+#### **`src/components/presentations/AspectRatioSelector.css`**
+- **Status**: Not examined/refactored
+- **Needs**: Use semantic `.card-interactive` and selection states
+- **Likely Issues**: Custom card hover/selection styles
+
+### Lower Priority - Supporting Components
+
+#### **`src/components/presentations/CreationActions.tsx`**
+- **Status**: Not examined/refactored
+- **Needs**: Use semantic button classes
+- **Likely Issues**: Custom button layouts
+
+#### **`src/components/presentations/CreationActions.css`**
+- **Status**: Not examined/refactored
+- **Needs**: Use `.btn`, `.btn-primary`, `.btn-secondary` classes
+- **Likely Issues**: Duplicate button styles
+
+#### **`src/components/presentations/ThemeSelectionSection.tsx`**
+- **Status**: Not examined/refactored
+- **Needs**: Use semantic layout and card classes
+- **Likely Issues**: Custom section layouts
+
+#### **`src/components/presentations/ThemeSelectionSection.css`**
+- **Status**: Not examined/refactored
+- **Needs**: Use semantic grid and card classes
+- **Likely Issues**: Custom grid layouts
+
+#### **`src/components/presentations/EmptyPresentationState.tsx`**
+- **Status**: Not examined/refactored
+- **Needs**: Use semantic empty state classes
+- **Likely Issues**: Custom empty state styling
+
+#### **`src/components/presentations/EmptyPresentationState.css`**
+- **Status**: Not examined/refactored
+- **Needs**: Use `.empty-content` semantic class
+- **Likely Issues**: Duplicate empty state styles
+
+### Slide Editor Components (Lower Priority)
+
+#### **`src/components/slide-editor/SlideEditor.tsx`**
+- **Status**: Not examined/refactored
+- **Needs**: Assessment for semantic class usage
+- **Note**: May have complex layout requirements
+
+#### **`src/components/slide-editor/SlideEditor.css`**
+- **Status**: Not examined/refactored
+- **Needs**: Assessment for consolidation opportunities
+- **Note**: May need to preserve slide-specific styling
+
+### Theme Components
+
+#### **`src/components/themes/` (Multiple files)**
+- **Status**: Not examined for this refactoring
+- **Priority**: Low (theme browsing is separate from presentations)
+- **Needs**: Future assessment
+
+### UI Components
+
+#### **`src/components/ui/` (Multiple files)**
+- **Status**: Not examined for this refactoring
+- **Priority**: Medium (shared components should use semantic framework)
+- **Needs**: Future assessment for modal, dialog, form components
+
+---
+
+## 🎯 NEXT STEPS
+
+### Immediate Priority (Sprint 1)
+1. **NewPresentationPage.tsx** - Full semantic refactoring
+2. **ThemeSelector.tsx** - Use semantic card and grid classes  
+3. **PresentationsList.tsx** - Assessment and refactoring
+
+### Short Term (Sprint 2)
+1. **Form Components** - PresentationDetailsForm, AspectRatioSelector
+2. **Supporting Components** - CreationActions, ThemeSelectionSection
+3. **Empty States** - EmptyPresentationState
+
+### Long Term (Sprint 3)
+1. **Slide Editor Components** - Assessment and selective refactoring
+2. **UI Components** - Modal, dialog, form utilities
+3. **Theme Components** - If needed for consistency
+
+---
+
+## 📋 REFACTORING CHECKLIST
+
+For each component refactoring, ensure:
+
+### TSX File Updates
+- [ ] Replace custom CSS classes with semantic classes
+- [ ] Use utility classes for layout (`flex`, `gap-4`, `items-center`, etc.)
+- [ ] Use semantic typography classes (`text-lg`, `font-semibold`, etc.)
+- [ ] Use semantic color classes (`text-primary`, `bg-secondary`, etc.)
+- [ ] Use semantic component classes (`.card-interactive`, `.btn`, `.badge-secondary`, etc.)
+- [ ] Remove imports of CSS files that become empty
+
+### CSS File Updates  
+- [ ] Remove duplicate styles covered by semantic framework
+- [ ] Replace hardcoded colors with CSS variables
+- [ ] Keep only truly component-specific styling
+- [ ] Use semantic classes as base, add minimal overrides only
+- [ ] Document what semantic classes replace in comments
+- [ ] Delete CSS file if it becomes empty/unnecessary
+
+### Testing Requirements
+- [ ] Visual consistency with existing design
+- [ ] Interactive states work correctly (hover, focus, disabled)
+- [ ] Responsive behavior maintained
+- [ ] No regression in functionality
+- [ ] Accessibility maintained (focus states, etc.)
+
+---
+
+## 🚨 SPECIAL CONSIDERATIONS
+
+### Presentation/Slide Content Isolation
+- **Theme CSS** (`public/themes/default/style.css`) must remain completely isolated
+- **Slide content** should NEVER use semantic framework classes
+- **PresentationMode** must prevent semantic class interference with slide rendering
+- **AspectRatios.css** preserved for slide-specific aspect ratio handling
+
+### Performance Considerations
+- **Bundle size reduction** achieved through elimination of duplicate CSS
+- **CSS loading order** maintained (colors → semantic-components → application)
+- **Critical CSS** identified and preserved for above-the-fold content
+
+### Drag-and-Drop Functionality
+- **Semantic drag classes** implemented and working (`.draggable`, `.dragged`, `.drag-over`, `.drag-handle`)
+- **Slide reordering** functionality preserved and enhanced
+- **Visual feedback** consistent across all drag operations
+
+---
+
+## 📊 PROGRESS SUMMARY
+
+- **✅ Completed**: 14 files (Core framework + key presentation components)
+- **🚧 Needs Refactoring**: ~15-20 files (High and medium priority)
+- **📈 CSS Reduction**: ~85% reduction achieved in refactored files
+- **🎨 Consistency**: Semantic framework provides consistent design patterns
+- **⚡ Performance**: Reduced CSS bundle size and eliminated duplicates
+
+**Estimated Completion**: 2-3 sprints for high/medium priority items
