   weight-range request for it. The UA default of bold on h1-h6 therefore has
   no real face to bind to, so the browser synthesizes one by smearing the
   outlines, which reads as a blurry, badly-drawn serif. Pinning the weight
   keeps every heading on the drawn face. Headings set in --font-body override
   this by class, as they should. */
