/* Richie interface. D29: readability first - high contrast, tabular figures, large key totals, status by word +
   colour + shape of the mark, no emoji. Look: dark tinted base with a faint grid, Manrope for text, Exo 2 italic
   for page titles and key totals only, JetBrains Mono for small labels; four colour themes on one structure.
   Spacing: one scale tied to the font size (--s1..--s5); controls and cells pad in em of their own text. */
