Thanks for helping identify my first ever hotfix! There was bound to be an issue given this is my first real solo web development project - the background animation was causing the CPU issue as I immediately suspected. I've just pushed a fix that resolves this, along with extending the completion timer to 5 seconds for better readability. This timer adjustment is a temporary solution until I can implement a more configurable system.
Something is still not right for me. The scrolling is extremely janky. I'm on mobile so can't check devtools right now, but I would open up Chrome's Rendering tab in devtools and check for excessive layout recalculations and such. Maybe also do some performance profiling
