   gap grows by more than about half an em). English only in long-form text, whose lines hold 60 or more
   characters (articles, the privacy policy, the About story), from 640px and with hyphenation: in the
   shorter leads and blurbs a single long word can leave a gap of nearly an em, so they stay ragged.
   Headings, captions, one-line card text and form text stay start-aligned. */
