Tips

1. Use ASCII sparingly - Great for tech/dev presentations, can feel dated otherwise
2. Stick to brand colors - Don't mix custom colors, use the 5-color palette
3. Big text on title slides - h1 should be 4-5rem minimum
4. One idea per slide - Neobrutalism works best with focused content
5. Test interactivity - Always preview HTML before exporting
