Interactive Avatar Studio with Dynamic Profession Customization

The homepage will feature an Interactive Avatar Studio where users can see a live preview of their avatar as they customize it. The standout feature will be a dynamic profession customization tool:

• Profession Selector: Users can type in any profession (e.g., "Astronaut," "Chef," "Artist") and the system will generate a default look based on that profession.
• Customization Options: Users can then tweak every detail—uniforms, tools, accessories, and more—to make the avatar uniquely theirs.
• Interactive Animations: As users adjust features, the avatar will animate subtly (e.g., a chef’s hat bouncing, an artist’s brush painting a stroke).
• Background Themes: Users can select or design a background that complements their avatar’s profession.

The landing page will also feature a carousel of pre-designed avatars, showcasing the diversity and creativity possible with the tool.
