/* ============================================================================
   testing/explore · xp.css · the six tests' Explore pages

   /testing/comprehensive-genomic/, carrier-screening/, newborn-screening/,
   sports-performance/, gut-microbiome/, oral-microbiome/ (fragments named
   explore.html). The layout follows the site's own pages (testing/genetic for the bar, the
   two tone headings and the ink sections).

   Scoped to `.xp` on <body>. One page sheet for six pages: a test differs
   only by its accent (`.xp-cg` … `.xp-oh` on <main>'s first div).

   THE IDEA. The kit sits in the hero like an object on a lab bench; below it
   the page alternates paper and ink, and every number on it is set large and
   counts in once, because the numbers are the argument.
