**Current CSS-related issues:** 1. Font Loading Optimization Required - Fonts are directly embedded as Data URLs in dist/index.css - This unnecessarily increases the CSS file size, potentially impacting website loading performance - Need to separate font files for optimization 2. Theme Support Addition - Color values are currently hardcoded in CSS, making theme customization difficult - Need to implement a theming system for user customization **Improvement Direction:** - Separate and optimize font files - Implement CSS variables or theming system
