• Upload Interaction: Optimized image upload logic. Clicking on an uploaded image now triggers re-upload/replace instead of just opening crop, making the operation more intuitive.

🐛 Bug Fixes

• Schematic Download: Fixed an issue where clicking the Schematic download button in the preview box might have no response.

🚀 New Features

• Hybrid Palette: Introduced hybrid palette support for significantly improved color accuracy.
• Real-time Rotation: Added support for real-time image rotation preview in the editor.

🐛 Bug Fixes

• Schematic Import: Fixed an issue where importing certain .schematic files could fail.
• Stability: Fixed an issue where clicking might have no effect in certain situations.

🚀 New Features

• 3D Preview: You can now visualize your map art in 3D directly in the browser before exporting. This helps in verifying the stair-casing effect.
• Command Generation: Generate /setblock or /fill commands to directly build your pixel art in the game without downloading map files.
• Staircase Mode: Support for height-based shading (staircasing) to achieve much richer color depth using surface height variations.

⚡ Performance

• Web Workers: All image processing and color matching operations have been moved to Web Workers, ensuring the UI remains responsive even when processing large 4K images.
