 * rest are the portal bundle's tokens, and only pages that run the bundle have
 * them; a data space's own documents and the vendor's application load this
 * stylesheet on its own, where an unresolved `var()` is not a fallback to the
 * default but an invalid declaration — which is how the home came to have a
 * transparent footer while every portal screen had a navy one. The second name
 * in each chain is the published palette in `/shared/theme.css`, which every
 * page does serve.
