/* ==========================================================================
   «Двойчы» — the design direction.

   Every headword is set twice: Cyrillic, then Łacinka underneath in a serif
   italic. Belarusian was written in both alphabets and one of them was
   suppressed; the doubling is the argument of the site, so it is the one place
   the design spends its boldness. Everything else stays flat and quiet — solid
   fields of colour, no shadows, no rounded corners, no rotating accent hues.

   The doubling is a citation, not a conceit: Naša Niva ran as two parallel
   editions, Cyrillic and Łacinka, from 1906 until issue 43 of 24 October 1912,
   when it went Cyrillic-only. This page carries both editions at once.

   The second structural device carries information rather than decoration:
   a term's card is a filled violet field when the entry is written up in full
   and an empty outline when only the definition exists. The base is openly
   unfinished and the page says so.
