This plugin automatically generates a visual avatar for users who have not uploaded a custom profile picture. It is designed for site administrators who want to maintain a consistent, branded visual identity in comment sections and user profiles without relying on external services. The avatar is created using the first character of the user's display name, providing a clean, identifiable placeholder.

• Front-end Generation: All avatar creation happens directly in the user's web browser. This eliminates server-side processing and prevents the generation of cache files on your server, keeping it lightweight.
• Broad Language Support: The system correctly handles and generates avatars for names in various languages, including Chinese characters, not just the Latin alphabet.
• Minimal Footprint: The entire plugin is very small, around 5KB, ensuring it has a negligible impact on your site's loading speed and performance.
• Simple Integration: After activation, the plugin works automatically with themes that use the platform's standard get_avatar() function to fetch user images, requiring no configuration.
• Color Variety: Avatars are generated with a diverse and visually distinct set of background colors, making each one unique without manual input.
