Does it support text-based animations?

Absolutely. It includes helper utilities specifically designed to render outlined text, ensuring that words remain legible even when scaled down to emoji dimensions (128x128).

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

The skill uses aggressive color quantization (reducing palettes to 32-48 colors), limits frame counts to 10-15, and includes automatic validators that warn you if the output exceeds Slack's strict limits.

Can I combine different animation effects?

Yes, the animation primitives are fully composable. You can layer effects like 'bounce' and 'shake' simultaneously to create complex, custom motion paths.

What is the difference between Message and Emoji modes?

Message mode optimizes for 480x480 resolution and a 2MB limit, while Emoji mode uses more aggressive compression and smaller dimensions to fit the 64KB requirement.
