/* Shared styling for the /specs reference pages.
   Same palette and type as the landing page — these are the same product,
   and a reader arriving from Google should not feel dropped onto a
   different site. Kept in one file rather than inlined per page so a
   palette change is one edit, and so the six pages share a cache entry. */
