/* Half-Life Practice: a counting-lab bench. Pale sage bench top, a Geiger counter's dark olive case for the controls
   with a uranium-glass lime readout for the chosen course, deep bottle-green actions, a halving staircase beside the
   title, and graphs on white graph paper (green-grey grid, bottle-green curve, crimson dashed construction lines in
   the key) in both themes, as on paper. On paper everything prints black and grey on white. */
