Backgrounds, except for 'rose', use custom animated elements that automatically stop when inactive to help prevent memory leaks. No major performance issues have been reported.
The 'dot' background can be CPU-intensive and may cause slowdowns or increased fan noise on less powerful devices (#1, antfu/antfu.me#86). Although adjustments have been made to reduce its resource usage (8fb85e1), the impact may still be noticeable. Consider using a different background if performance becomes an issue.
Please report any problems you encounter. You can also customize the animation effects by modifying the constants in the corresponding components under src/components/backgrounds/.
