/* carsbuyusa.com
   Deliberately committed to a single light appearance: this site gets screenshotted and printed
   by compliance departments, and a page that looks different depending on the reader's OS setting
   is a page whose screenshots disagree with each other.
   System fonts only -- no external requests, so the page renders identically offline, behind a
   corporate proxy, or inside a strict content-security policy. */
