      h2 Font Sizes
      p.
        The following atoms adjust font size. All atoms use #[b em] units,
        so the font sizes will scale according to their parents.
      p.
        The first list shows atoms prefixed #[code fz-], which change only font size,
        mainly used for inline (text-level) elements.
        The second lists atoms prefixed #[code fzb-], for font-size/line-height combos,
        which are useful for maintaining vertical rhythm on block elements.
      p.
        Notice there are two pairs of classes for each size.
        The first classname has an
        #[abbr(title="Système International d’Unités" lang="fr") SI]
        prefix that corresponds to a power of 1000,
        while the second classname (highlighted) uses a Greek/Latin prefix that indicates
        the value of #[code font-size] in its definition.
        The first set is good for comparing two different atoms, and
        the second set is good for when you need to know the absolute size.
