What the model said

Done! I've improved the code with these changes:

1. **Config object** - Centralized colors, storage keys, and key mappings for easy customization
2. **DOM object** - Grouped all DOM references together for clarity
3. **State object** - Organized all state variables (index, hover capability, reduced motion preferences) into one place
4. **Cleaner event handling** - Extracted complex keyboard logic into `handleKeyDown()` and help button logic into `toggleKeyHintVisibility()`
5. **Better function organization** - Grouped all event listeners at the end for easier scanning
6. **Simplified logic** - Minor cleanups like the `applyColor()` function while maintaining the same behavior

The refactored code is more maintainable and makes it easier to customize colors, storage keys, or haptic feedback in the future. All accessibility and interactive features remain intact.
