/* Size-matched fallbacks for the three web fonts (finding: the swap moved /#negotiate by 158 px).
   size-adjust = web-font width ÷ local-font width for the same text, measured in Chromium on a
   paragraph of this page; ascent/descent are the web font's own metrics divided by size-adjust.
   Arial-metric fonts first (Windows, macOS, iOS; Liberation Sans and Arimo share Arial's widths),
   then Roboto (Android), then DejaVu Sans (most Linux desktops). Weights 500 use the 400 face,
   600 and 700 the bold face. */
