Describe the bug

For systems that enable users to toggle themes (dark/light) - seems like it is not possible to use the "class" mode for darkMode.
This makes sense to some extent due to Shadow DOM, I wonder though if we can maybe have some discussion around it and perhaps workaround it.
Maybe for a start an update to the documentation is needed + excluding this mode from the allowed modes for web-components.

For "media" based configuration - this works perfectly fine, as the configuration is not derived from a specific selector.

One possible workaround is disabling the Shadow DOM for the element, however this is probably not the best approach, in addition to losing key features such as slots.

Severity

blocking all usage of Twind

One way I thought of resolving this was to use Lit context provider, and consume it in every component.
This works, however this obviously adds overhead and boilerplate to each component.
