   testing/microbiome · mb.css · loaded AFTER testing/genetic/dna.css

   The page wears the genetic page's design as it is: same sheet, same script,
   same sections. This file only covers what the microbiome content asks of it
   that the genetic content never did, scoped to `.mb` on <body>:
     · a row of four standards under the hero,
     · three kits in the bento instead of four, with longer sentences,
     · a label and four figures on the off grid window,
     · the balance pair in the comparison table's place.
   COPY RULE, page wide: no dashes, no connecting hyphens, no all caps.
