All payload css is now encapsulated inside CSS layers under `@layer
payload-default`
Any custom css will now have the highest possible specificity.
We have also provided a new layer `@layer payload` if you want to use
layers and ensure that your styles are applied after payload.
To override existing styles in a way that the existing rules of
specificity would be respected you can use the default layer like so
```css
@layer payload-default {
// my styles within the payload specificity
}
```
