Can I combine multiple animation effects?

Yes, the toolkit features composable primitives, allowing you to layer multiple effects such as 'bounce' and 'shake' simultaneously to achieve complex, creative motion.

How does this skill handle Slack's 64KB emoji limit?

The skill uses aggressive optimization strategies, including limiting color palettes to 32-48 colors, reducing frame counts, and providing real-time size validation to ensure emojis meet strict requirements.

Does it support custom branding or colors?

Yes, it includes a color management system with pre-made palettes and support for custom RGB values, along with outlined typography tools for better brand visibility.

What types of objects can I animate?

You can animate standard emojis, text, basic shapes, or custom image frames using the provided drawing and interpolation utilities.
