Bug description

The Swiper Element (Web Component) does not have parts for its sub-components, as its pagination (pagination button (normal / active)), navigation, etc.
This makes styling those elements unnecessarily hard, as selecting those elements in shadow DOM by CSS is not directly possible from the outside.

Expected Behavior

All sub-components should be parts, so that styling is very easy and efficient,
it also leverages the strengths of such web components.

Actual Behavior

No parts are available.

Swiper version

9.2.3

Platform/Target and Browser Versions
