That’s great, thanks for sharing this. Looks like a solid and very well thought out starter theme. Just some questions:

Is it full site editing compatible or plans for this?

Plans to remove SASS and use modern CSS?

Confirm UI components like tabs and accordions are not blocks so not for end user?

Why use it’s own lazyload library when WP and most browsers already have lazy load?

Not much mention of accessibility, is this something that is built into the starter theme and components?

Is their ui components for form builder or just plugins used for that like CF7?

Thank you!
