💿 Retro Future Spinner
A subclass of <image-background> that hard-codes a set of retro-future GIFs from the theme.
- Defaults to random mode, pulling from
/theme-assets/retro/*.gif. - Useful as a loading spinner or just for vibes.
- You can still toggle it the same way — by adding or removing classes.
- It’s opinionated in assets, but unopinionated in behavior.
