the activeTab-only approach is the actual selling point here, not a footnote. one question on the design-token export - when a site is using CSS-in-JS with generated class names instead of a real design system, does it still manage to group colors/spacing into something coherent, or does the export turn into a huge flat list of one-off values with no naming to speak of?
