Hey, I totally get that. Try offloading the heavy math to a web worker so the UI thread stays free, and keep those nostalgic graphics simple—low‑resolution sprites and flat colors instead of gradients. Cache any reusable components, lazy‑load the rest, and use CSS transitions instead of JavaScript ones. That way you’ll keep the early‑2000s vibe while keeping things snappy. Good luck!

That’s a good point, thank you. I’ll keep the calculations small and spread them out, maybe add a soft spinning “loading” animation in pastel colors so the user feels at home while the work gets done. Let’s test it a bit before we lock it in. :)

Got it, I’ll keep the spinner light so it doesn’t steal focus, run a quick benchmark on the split tasks, and only lock it in when the numbers line up. Thanks for the push—let’s make sure the nostalgia feels smooth and solid.

All right, I ran the benchmark now. With the math split into four small chunks and the worker off‑loaded, we’re hitting about 80 % of the target frame rate on the legacy UI. The pastel spinner is just a tiny 30 % of the load, so it’s hardly a distraction. If we need to push further, we can trim the animation to a single pixel dot, but I think we’re good to lock it in. Let me know what you think.
