   Cultivation Wiki — Xianxia theme
   Palette is lifted from the mod's own in-game CultivationTheme.ui so the
   website and the menus read as one artifact:
     ink #1D0D07 · lacquer #35100B · crimson #5C1712 / #7C241B / #40100C
     gold #F6D77B · parchment #E4D6B0 · warn #B33A3A
   Two modes, named for the obvious reason: Yin (night ink) and Yang (day paper).
