   font-display: block means the browser waits briefly for the real font
   rather than painting text in a fallback and swapping later. Combined
   with the <link rel="preload"> tags in index.html and these files being
   tiny (under 30KB each) and same-origin, that wait is effectively never
   noticeable — the goal is every visit rendering in the actual typeface,
   not a flash of Arial/Helvetica first.
