/* Metric-matched fallbacks, so the swap from Arial / Courier to the webfont
   does not move a line. Liberation and Arimo / Cousine are Arial's and Courier
   New's metric twins: a machine with neither Arial nor them (most Linux) fell
   to a wider face, and a tool site's header moved 3-5px at the swap.

   Inter narrows as optical sizing follows the font size, about 9% from 14px to
   32px, and widens with weight, so one face cannot match it. Text gets faces
   measured at 16px, display type faces measured at 32px and up, each weight
   band its own Arial cut. Measured on docs prose in Chrome; ascent and descent
   keep Inter's line box at every size-adjust. JetBrains Mono and Courier New
   share one advance, 0.6em, so the mono face is not scaled. */
