Adding to Marcus's answer: another huge benefit of isolating{' '}
<code className="bg-muted text-foreground rounded px-1.5 py-0.5 font-mono text-xs">

is for monorepos or dual-framework setups.
</p>
<p>
When you have both Vue and React registry components (like in UIPKGE), the variant definitions can
be shared verbatim in a shared token package without bringing in any Vue SFC or JSX compiler
dependencies. This keeps design tokens consistent across both stacks.
