• submissions/examples/ease-text-scramble/style.css
• submissions/examples/ease-text-scramble/README.md

How it works

• ~15 lines of JS drives a requestAnimationFrame loop.
• Each frame scrambles unrevealed characters; revealed ones stay fixed.
• Scramble duration is 2s; can be replayed with a button.
• Green-on-black terminal style via CSS.
• Respects prefers-reduced-motion.

EaseMotion classes used
ease-btn, ease-btn-primary, ease-hover-scale-105, ease-fade-in, ease-delay-,
ease-container, ease-flex, ease-text-, ease-bg-gray-900, ease-p-*, etc.

Custom CSS (>5 lines) for scramble demo styling and accessibility.
