/* =====================================================================
   LLModel.com design system
   Palette: viridis (the colormap ML plots live in) on cool plot-paper.
   Type: Archivo (UI + display, width axis), Newsreader (long-form reading),
         Martian Mono (tokens and code).
   Motif: text split into tokens. Used for the wordmark, the hero sampler
          and tags; everything else stays quiet.
