I can vouch for the paid content (and I paid the pre-pandemic price). As for the implementation, it's possible to apply the axiomatic styles to standard HTML (directly, or via React, Vue etc). The examples happen to use web components (custom elements) bc of author preference, I think. I prefer React bc it has a better SSR story and doesn't require JS to be enabled. As for semantic markup per se (a tangent, given my explanation above), your a11y efforts are waay better spent elsewhere.
