+# NPM to Yarn Migration Complete
+
+All npm commands have been successfully replaced with yarn equivalents across the project.
+
+## Files Updated:
+
+### 1. package.json
+- `"validate": "npm run lint && npm run build"` → `"validate": "yarn lint && yarn build"`
+- `"pretest": "npm run validate"` → `"pretest": "yarn validate"`
+- Package manager already set to `"packageManager": "yarn@1.22.19"`
+
+### 2. Dockerfile
+- `RUN npm install && npm cache clean --force` → `RUN yarn install --frozen-lockfile && yarn cache clean`
+- `RUN npm run build` → `RUN yarn build`
+- `RUN npm prune --production` → `RUN yarn install --production --frozen-lockfile`
+
+### 3. .github/workflows/ci.yml
+- Node.js cache changed from `'npm'` to `'yarn'`
+- `npm install` → `yarn install --frozen-lockfile`
+- `npm run lint` → `yarn lint`
+- `npm run build` → `yarn build`  
+- `npm run validate` → `yarn validate`
+
+### 4. .claude/settings.local.json
+- All npm-related Bash permissions updated:
+  - `"Bash(npm run typecheck:*)"` → `"Bash(yarn typecheck:*)"`
+  - `"Bash(npm run type-check:*)"` → `"Bash(yarn type-check:*)"`
+  - `"Bash(npm run lint)"` → `"Bash(yarn lint)"`

+
+### 5. Memory Files Updated
+- `.serena/memories/docker-traefik-ssl-complete-setup.md`: Updated management commands and build process references
+- `.serena/memories/typescript_migration_complete.md`: Updated build process documentation
+
+## Benefits of Yarn Migration:
+- Deterministic dependency resolution with yarn.lock
+- Faster installs with better caching
+- More reliable CI/CD builds with --frozen-lockfile
+- Better workspace support (if needed in future)
+- Consistent package management across development and production

+# Thumbnail Quality Improvements Completed
+
+## Problem Identified:
+- SoundCloud thumbnails were displaying in low resolution (100x100px with "-large" suffix)
+- Poor visual quality affecting user experience
+
+## Solution Implemented:
+
+### 1. **Enhanced Thumbnail Resolution Function**
+Added `getHighQualityThumbnail()` method in `src/soundcloud.ts`:
+- Automatically upgrades `-large` (100x100) to `-t500x500` (500x500)  
+- Upgrades `-crop` (400x400) to `-t500x500`
+- Upgrades `-t300x300` to `-t500x500`
+- Custom high-quality placeholder for default avatars
+- Fallback handling for various URL formats
+
+### 2. **CSS Image Rendering Optimization**
+Updated `public/style.css`:
+- Added `image-rendering: optimizeQuality` for crisp thumbnail display
+- Applied to both desktop and mobile thumbnail styles
+- Maintains responsive design while improving visual quality
+
+### 3. **Automatic Quality Detection**
+The system now:
+- Detects SoundCloud thumbnail URL patterns
+- Automatically requests highest available resolution
+- Gracefully handles missing high-res versions
+- Provides quality placeholders when needed
+
+## Technical Details:
+- **Resolution upgrade**: 100x100 → 500x500 (25x more pixels)
+- **Browser optimization**: Enhanced image rendering properties
+- **Fallback safety**: Original URLs preserved if upgrade fails
+- **Performance**: No additional API calls, just URL manipulation
+
+## Results:
+- Much sharper, clearer thumbnail images
+- Better visual consistency across different track types
+- Improved user experience without performance impact
+- Maintains compatibility with all existing functionality
