/* Shared by every biovanta.llc lead page. The look follows biovanta.store:
   the wide-tracked wordmark in a cream pill, an espresso band for the
   statement, a light line over a bold one, warm cream underneath.
   One accent: --flag. It marks what a reader should distrust (a hidden key,
   a "no" answer, a shortfall) and errors. Nothing else is red.
   Radii: surfaces 10px, controls 999px. */
