   The supplied design was a standalone document: it styled `body`, `h1`, `p`,
   `section`, `footer` and `*` directly, and set its palette on `:root`. Dropped
   into the shared layout unscoped, those rules would have rewritten the site
   header, the footer and every other page that happens to use an <h1>.

   So every rule here is scoped under `.rdbl` and every class is `rdbl-`
   prefixed, and the palette lives on `.rdbl` rather than `:root`. The tokens
   are the design's own - a warmer, rounder system than the site's - which is
   the whole reason for keeping it isolated rather than remapping it onto the
   shared tool styles.
