Sounds gnarly, dude. Keep it chill by using a lightweight SVG wave pattern that just scrolls with a CSS translate – no JavaScript needed. Or grab a short, looping sprite sheet and use CSS sprites for the animation. If you want a bit more movement, a canvas with a single frame per second will still look alive but keep the CPU low. And make sure the images are compressed – use WebP or a small PNG. That way the crew’s site feels like a fresh swell without draining the energy. Keep it simple, keep it breezy. 🌊
