     Uzbek and English headings share one face and one size (client feedback: the Russian pages
     are the reference). Futura Condensed has no Cyrillic; swap in ParaType Futura PT Cond here
     once it is supplied.

     font-display: block, not swap. Swap paints the fallback first and changes it a moment later,
     and a headline in the wrong face for a moment — condensed against not-condensed — is exactly
     what the client objected to. Block waits instead. It can do that because every one of these
     is preloaded in base.html, same-origin and subset to about 20 KB, so it is there by the time
     there is anything to paint; and if one ever fails to arrive, the fallback still appears after
     three seconds rather than never. */
