/* =========================================================================
   日本語道 — washi papír ve dne, noční inkoust v noci
   -------------------------------------------------------------------------
   Barvy jdou přes dvě vrstvy. Nejdřív odstíny, které jsou v obou motivech
   stejné (rumělka, indigo, matcha…), pod nimi významové proměnné, které se
   v tmavém motivu přepíšou. Drtivá většina pravidel dál sahá jen po var(--…)
   a o motiv se starat nemusí.

   Pravidlo pro každé nové pravidlo: žádné natvrdo psané #fff, #000 ani
   rgba(255,255,255,…) — vždycky token. Jinak to v jednom z motivů zmizí.

   Hry jsou výjimka: drží si noc pořád. Jejich kulisy jsou hvězdná obloha,
   měsíc a siluety vesnice, na papíře by z toho byla kaše. Obstarává to
   :root[data-theme]:has(.game) dole.
