   * Measured on https://kb.drakesoftware.com/kb/Drake-Tax/16072.htm with CDP:
   *     body  font-family: Arial, Avenir, Myriad   16px   line-height 27.2px
   *     h1    font-family: "open sans"             24px   bold  #1b75bc
   *     h2    font-family: Arial, Avenir, Myriad   19.2px bold  #1b75bc
   *     li/p                                       16px
   * i.e. the ONLY thing on the live KB that asks for Open Sans on screen is h1
   * (`h2 { font-family:'open sans' }` exists only inside @media print), and
   * because Drake ships NO @font-face and NO webfont import, that h1 request
   * resolves to nothing and the browser substitutes its default face.
   *
   * The previous value here ("Source Sans Pro", "Segoe UI", …) was invented by
   * us — Drake never specifies either family, and neither is installed on a
   * stock macOS/Linux box, so it was silently rendering as plain Arial anyway.
