Fixed 22 ESLint errors across 26 Vue component files: - Removed TypeScript type annotations from ReadingProgress.vue (converted to JS) - Removed unused variables, imports, and duplicate function declarations - Fixed HTML parsing errors (invalid attribute names, unclosed tags) - Added missing :key directives to v-for loops - Fixed duplicate object keys (backgroundImage) - Replaced special characters in comments to avoid parsing issues - Fixed malformed HTML tags (v-else", 003e attributes) All warnings were left unchanged as requested. Build now passes with 0 errors. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
