  Fonts:
    Cormorant Garamond -- headings. Old-style, genuinely distinguished, used in 
                          serious academic publishing. Not a web default anywhere.
    Work Sans          -- body. Geometric but warm, much less used than Inter.
    Fira Code          -- data labels, mono values. Warm and readable at small sizes.
