[preview card] Reduce bundle size with "interestfor" API?

## Summary

Considering that the platform has* ([experimental at this date](https://developer.mozilla.org/en-US/docs/Web/API/HTMLButtonElement/interestForElement)) a built-in feature for this component https://developer.mozilla.org/en-US/docs/Web/API/Popover_API/Using_interest_invokers: `interestfor`, a developer might wonder: can't we simplify this component down to be lighter?

The answer is probably no, but it feels like having a space for the community to shine in could be great.

With this native feature, a lot is configured via CSS, for example #3519, solved with:

```css
[interestfor] {
interest-delay-start: 0.3s;
}

.parent:has(:interest-source) [interestfor] {
interest-delay-start: 0s;
}
```
