/* METRIS — one stylesheet for every page.

   The type does the work. Three sizes that are genuinely different, not five
   that are nearly the same: a display headline, serif body at reading size, and
   a small monospace label in green for structure. Green is structural, not
   decorative — it marks where you are, never fills an area.

   Palette and fonts are fixed: near-black, paper, one green. No gradients, no
   shadows, no third colour. */
