Thanks so much for your work, the components look great and straightforward to use. Next time I'm building something will definitely try to give Shoelace a spin.
Can I ask, are ARIA attributes handled by default?
Perhaps this isn't as specific of an answer as you're looking for, as I'm not too familiar with the Shoelace library, but perhaps we gain some insight from the Shoelace Accessibility Commitment.

The goal is to handle as much accessibility as possible with smart defaults and by making it easy for users to get right. Currently, all aria stuff is handled internally the components. For example, look at <sl-input> and you’ll see that the input, label, and help text are automatically linked in the shadow root. The minimum the user needs to provide is a label and assistive devices work as expected.
