/* ---------------------------------------------------------------
   Immer wieder Deutsch — base styles

   Design language (keep to these rules when adding anything):

   1. One ground. Everything sits on warm washi paper. There are no
      floating coloured cards.
   2. Separate with space and hairlines, never with blocks of colour.
      A filled panel is reserved for a genuine aside (host bio,
      closing notes) and uses --paper-deep only.
   3. Palette is four earthy colours from Sanzo Wada's "A Dictionary
      of Color Combinations": paper, sumi ink, an Antwarp-blue indigo
      as the single accent, and a moss green as the quiet second.
      Clay is used rarely, for small marks only.
   4. Display type is Zen Old Mincho (a Japanese serif); UI and body
      copy are a plain humanist sans. Small labels are letterspaced
      uppercase.
   5. Corners are nearly square (3px). Generous line-height and
      whitespace do the work instead of decoration.
