/* All three faces are self-hosted and preloaded (SIL OFL 1.1, assets/fonts/*-OFL.txt).
   Anybody (display): headings wait for it instead of swapping in front of the reader (header.php).
   Instrument Sans and JetBrains Mono (text, code): font-display optional, so text never swaps
   mid-read: if the preloaded font isn't there for the first paint, that page view keeps the
   size-matched fallback below and the next page has it from the cache. */
