- Remove entrance animations (animate-in, fade-in, zoom-in) from all components
- Remove scale effect (active:scale-[0.99]) from clean button
- Remove transition effects (transition-all, transition-colors) from OptionItem, StorageOptionsGrid, AutoRefreshToggle
- Remove bouncing animation from error icon
- Remove pulsing animation from warning banner
- Keep animate-spin on button loading spinner as functional indicator
