- Updated Project.tsx to utilize the new createHandleDrop function, improving readability and maintainability.
- Enhanced styling for the scene container and real-time visualization components to improve layout and responsiveness.
- Removed unnecessary styles and consolidated button and input styles for consistency.
- Cleaned up unused imports and variables in various files to streamline the codebase.
