   TIER 2. A short paper: running head, abstract, numbered sections,
   column-measure text, figure-and-caption units at column width. Colour
   encodes data or is absent (sc-r2): the only hues on the page live inside
   the figures, where they encode grade category. Serif text, sans figure
   labels (ours, declared). No emphasis unwarranted by the data.
