/* The title in the site's own display type — the hero's rule (styles/layout.css,
   `.hero h1`): the same weight, tracking and leading, so the two headlines read
   as one voice on a Mac, an iPhone and an Android now that the section inherits
   the site's face (Khusan, 17 Sep: "aligned with our text style … in terms of
   font we chose and kerning"). It was 400 at -.042em, the "1%" tighter still.
   One line at every width, sized by the column it sits in: at this weight and
   tracking the text runs about 10.4× the font size, so beside the docked
   stage (the two-column grid, 901px and up) the size is capped at 4.2vw of the
   viewport — about the column's width over 10.4 — and on the stacked layout,
   where the copy has the whole width, at 8.6vw. Between 901 and ~1200px the
   grid leaves the copy 218–381px (the stage column keeps a 520px minimum), and
   no readable size fits nineteen characters there — the old title overflowed
   that band by 100px+ and was clipped — so beside the stage the title may wrap
   to two lines ("1% Product / Designer", as the hero's headline is two);
   stacked, it is one line, nowrap. Measured 17 Sep at 320–1920. */
