What is Kobalte?

Kobalte is a UI toolkit for building accessible web apps and design systems with SolidJS. It provides a set of low-level UI components and primitives which can be the foundation for your design system implementation.

It seems that <details> and <summary> aren't flexible enough for Kobalte's implementation and flexibility.
Closing as not planned since the current implementation is already fully accessible.
Will reconsider if native <details> become more flexible.
