/* OncoFix — product page.

   Clinical rather than corporate: a lot of white, a deep navy that reads as
   hospital signage, and one clay-red used only where the product itself
   would use it — to say "this one needs a second look". Nothing on this
   page is allowed to look like a diagnosis, so the red never appears
   beside a number and never appears alone. */
